Understand IPv4 or interner protocol verison 4 datagram header format. All fields explained in detail with examples containing version number, header length, DSCP, datagram length,Identifier, flags, fragmentation offset, time to live, protocol, header checksum, source and destination IP address, and Options. Data or payload contains the transport layer segment.
Notes : https://techterms.in
Facebook : https://www.facebook.com/DGTechTerms/
Version number specifies the version of datagram - version 4 or version 6. The header length tells the total length of the IPv4 datagram header. The 'OPTION’ field is variable in length and is rarely used. DSCP classify IP packets. Datagram length tells the total length of the IP datagram. Identifier, flags, and fragmentation offset are used in case of IP fragmentation. Time-to-live field is used to limit the lifetime of an IP datagram. Protocol indicates to which transport layer protocol the data portion of the IP datagram should be passed. Header checksum helps in detecting the bit errors in the received IP datagram’s header. Source and destination IP address represents the IPv4 address of the source host and the destination host, respectively. Data (Payload) contains the segment of the transport layer.

IPv4 vs IPv6... Why do we need to transition from the Internet Protocol that's served us so well for all these years? Maybe because we're completely running out of IP addresses!

3.1.1 Διευθύνσεις IPv4
Το πρωτόκολλο IP ορίζει ότι οι υπολογιστές που συμμετέχουν σε ένα δίκτυο, χρησιμοποιώντας το συγκεκριμένο πρωτόκολλο (την έκδοση 4 - IPv4), αναγνωρίζονται με μοναδικό τρόπο από έναν 32μπιτο δυαδικό αριθμό, την διεύθυνση IP (IP Address).
Στην πραγματικότητα ένας υπολογιστής μπορεί να έχει περισσότερες διευθύνσεις,
μια διαφορετική για κάθε διαφορετικό δίκτυο στο οποίο είναι συνδεδεμένος.
Όπως μια γωνιακή οικία η οποία έχει πρόσοψη σε δυο δρόμους που διασταυρώνονται,
μπορεί να προσδιοριστεί με διαφορετικές διευθύνσεις
ανάλογα με το δρόμο από τον οποίο προσεγγίζεται.
Διεύθυνση IP έχει κάθε δικτυακή διεπαφή (Network Interface) ενός υπολογιστή.
Έτσι ένας υπολογιστής με δυο κάρτες δικτύου Ethernet (δικτυακές διασυνδέσεις) μπορεί να έχει δυο διευθύνσεις.
Διεύθυνση που προσδιορίζει μια δικτυακή διασύνδεση (έναν υπολογιστή) χαρακτηρίζεται "αποκλειστικής διανομής" (unicast)

When we type in an IP address, the computer will convert that into binary.
And to fully understand how IP addresses work, we need to be able to do the same.
An IPv4 address is 32 bits long. This means the address is made up of 32 binary digits. Each digit is called a bit. The IP address contains 4 octets. Each octet contains 8 binary bits.
Each bit can either be a 1 or a 0. A bit represents a value of 1, 2, 4, 8, 16, 32, 64 or 128. That value doubles in size from right to left. This is called the power of 2.
We also need to think about subnet masks. Previously I said, wherever there is 255, this is the network section and wherever there is a 0, this is the host section. That’s true in the simplest form, however, it can get a bit more complicated than that.
The real way to see which part of an IP address is the network section is by looking at the subnet mask binary bits and comparing it to the IP address binary bits. Anytime you see a 1 value, this bit is the network section and anytime you see a 0 it’s the host section.
Instead of the full subnet mask, you will often see it written as a forward slash, and then the number of network binary bits. For example, instead of 255.255.255.0, we could write it as /24. This is usually added to the end of the IP address.

IPv4 address exhaustion
IPv4 address exhaustion is the depletion of the pool of unallocated Internet Protocol Version 4 (IPv4) addresses, which has been anticipated since the late 1980s. This depletion is the reason for the development and deployment of its successor protocol, IPv6.
The IP address space is managed by the Internet Assigned Numbers Authority (IANA) globally, and by five regional Internet registries (RIR) responsible in their designated territories for assignment to end users and local Internet registries, such as Internet service providers. The top-level exhaustion occurred on 31 January 2011. Four of the five RIRs have exhausted allocation of all the blocks they have not reserved for IPv6 transition; this occurred on 15 April 2011 for the Asia-Pacific, on 14 September 2012 for Europe, on 10 June 2014 for Latin America and the Caribbean, and on 24 September 2015 for North America.
IPv4 provides approximately 4.3 billion addresses; a subset of these have been distributed by IANA to the RIRs in blocks of approximately 16.8 million addresses each. The depletion of the IPv4 allocation pool has been a concern since the late 1980s, when the Internet started to experience dramatic growth. The Internet Engineering Task Force (IETF) created the Routing and Addressing Group (ROAD) in November 1991 to respond to the scalability problem caused by the classful network allocation system in place at the time. The anticipated shortage has been the driving factor in creating and adopting several new technologies, including network address translation (NAT), Classless Inter-Domain Routing (CIDR) in 1993, and IPv6 in 1998. IPv6, the successor technology to IPv4 which was designed to address this problem, supports approximately 7038340000000000000♠3.4×1038 network addresses.

IPv4
Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet, and was the first version deployed for production in the ARPANET in 1983. It still routes most Internet traffic today, despite the ongoing deployment of a successor protocol, IPv6. IPv4 is described in IETF publication RFC 791 (September 1981), replacing an earlier definition (RFC 760, January 1980).
IPv4 is a connectionless protocol for use on packet-switched networks. It operates on a best effort delivery model, in that it does not guarantee delivery, nor does it assure proper sequencing or avoidance of duplicate delivery. These aspects, including data integrity, are addressed by an upper layer transport protocol, such as the Transmission Control Protocol (TCP).
Addressing
IPv4 uses 32-bit (four-byte) addresses, which limits the address space to 4294967296 (232) addresses. This limitation stimulated the development of IPv6 in the 1990s, which has been in commercial deployment since 2006.

Understand IPv4 or interner protocol verison 4 datagram header format. All fields explained in detail with examples containing version number, header length, DSCP, datagram length,Identifier, flags, fragmentation offset, time to live, protocol, header checksum, source and destination IP address, and Options. Data or payload contains the transport layer segment.
Notes : https://techterms.in
Facebook : https://www.facebook.com/DGTechTerms/
Version number specifies the version of datagram - version 4 or version 6. The header length tells the total length of the IPv4 datagram header. The 'OPTION’ field is variable in length and is rarely used. DSCP classify IP packets. Datagram length tells the total length of the IP datagram. Identifier, flags, and fragmentation offset are used in case of IP fragmentation. Time-to-live field is used to limit the lifetime of an IP datagram. Protocol indicates to which transport layer protocol the data portion of the IP datagram should be passed. Header checksum helps in detecting the bit errors in the received IP datagram’s header. Source and destination IP address represents the IPv4 address of the source host and the destination host, respectively. Data (Payload) contains the segment of the transport layer.

3.1.1 Διευθύνσεις IPv4
Το πρωτόκολλο IP ορίζει ότι οι υπολογιστές που συμμετέχουν σε ένα δίκτυο, χρησιμοποιώντας το συγκεκριμένο πρωτόκολλο (την έκδοση 4 - IPv4), αναγνωρίζονται με μοναδικό τρόπο από έναν 32μπιτο δυαδικό αριθμό, την διεύθυνση IP (IP Address).
Στην πραγματικότητα ένας υπολογιστής μπορεί να έχει περισσότερες διευθύνσεις,
μια διαφορετική για κάθε διαφορετικό δίκτυο στο οποίο είναι συνδεδεμένος.
Όπως μια γωνιακή οικία η οποία έχει πρόσοψη σε δυο δρόμους που διασταυρώνονται,
μπορεί να προσδιοριστεί με διαφορετικές διευθύνσεις
ανάλογα με το δρόμο από τον οποίο προσεγγίζεται.
Διεύθυνση IP έχει κάθε δικτυακή διεπαφή (Network Interface) ενός υπολογιστή.
Έτσι ένας υπολογιστής με δυο κάρτες δικτύου Ethernet (δικτυακές διασυνδέσεις) μπορεί να έχει δυο διευθύνσεις.
Διεύθυνση που προσδιορίζει μια δικτυακή διασύνδεση (έναν υπολογιστή) χαρακτηρίζεται "αποκλειστικής διανομής" (unicast)

When we type in an IP address, the computer will convert that into binary.
And to fully understand how IP addresses work, we need to be able to do the same.
An IPv4 address is 32 bits long. This means the address is made up of 32 binary digits. Each digit is called a bit. The IP address contains 4 octets. Each octet contains 8 binary bits.
Each bit can either be a 1 or a 0. A bit represents a value of 1, 2, 4, 8, 16, 32, 64 or 128. That value doubles in size from right to left. This is called the power of 2.
We also need to think about subnet masks. Previously I said, wherever there is 255, this is the network section and wherever there is a 0, this is the host section. That’s true in the simplest form, however, it can get a bit more complicated than that.
The real way to see which part of an IP address is the network section is by looking at the subnet mask binary bits and comparing it to the IP address binary bits. Anytime you see a 1 value, this bit is the network section and anytime you see a 0 it’s the host section.
Instead of the full subnet mask, you will often see it written as a forward slash, and then the number of network binary bits. For example, instead of 255.255.255.0, we could write it as /24. This is usually added to the end of the IP address.

Understand IPv4 or interner protocol verison 4 datagram header format. All fields explained in detail with examples containing version number, header length, DSCP, datagram length,Identifier, flags, fragmentation offset, time to live, protocol, header checksum, source and destination IP address, and Options. Data or payload contains the transport layer segment.
Notes : https://techterms.in
Facebook : https://www.facebook.com/DGTechTerms/
Version number specifies the version of datagram - version 4 or version 6. The header length tells the total length of the IPv4 datagram header. The 'OPTION’ field is variable in length and is rarely used. DSCP classify IP packets. Datagram length tells the total length of the IP datagram. Identifier, flags, and fragmentation offset are used in case of IP fragmentation. Time-to-live field is used to limit the lifetime of an IP datagram. Protocol indicates to which transport layer protocol the data portion of the IP datagram should be passed. Header checksum helps in detecting the bit errors in the received IP datagram’s header. Source and destination IP address represents the IPv4 address of the source host and the destination host, respectively. Data (Payload) contains the segment of the transport layer.

3.1.1 Διευθύνσεις IPv4
Το πρωτόκολλο IP ορίζει ότι οι υπολογιστές που συμμετέχουν σε ένα δίκτυο, χρησιμοποιώντας το συγκεκριμένο πρωτόκολλο (την έκδοση 4 - IPv4), αναγνωρίζονται με μοναδικό τρόπο από έναν 32μπιτο δυαδικό αριθμό, την διεύθυνση IP (IP Address).
Στην πραγματικότητα ένας υπολογιστής μπορεί να έχει περισσότερες διευθύνσεις,
μια διαφορετική για κάθε διαφορετικό δίκτυο στο οποίο είναι συνδεδεμένος.
Όπως μια γωνιακή οικία η οποία έχει πρόσοψη σε δυο δρόμους που διασταυρώνονται,
μπορεί να προσδιοριστεί με διαφορετικές διευθύνσεις
ανάλογα με το δρόμο από τον οποίο προσεγγίζεται.
Διεύθυνση IP έχει κάθε δικτυακή διεπαφή (Network Interface) ενός υπολογιστή.
Έτσι ένας υπολογιστής με δυο κάρτες δικτύου Ethernet (δικτυακές διασυνδέσεις) μπορεί να έχει δυο διευθύνσεις.
Διεύθυνση που προσδιορίζει μια δικτυακή διασύνδεση (έναν υπολογιστή) χαρακτηρίζεται "αποκλειστικής διανομής" (unicast)

When we type in an IP address, the computer will convert that into binary.
And to fully understand how IP addresses work, we need to be able to do the same.
An IPv4 address is 32 bits long. This means the address is made up of 32 binary digits. Each digit is called a bit. The IP address contains 4 octets. Each octet contains 8 binary bits.
Each bit can either be a 1 or a 0. A bit represents a value of 1, 2, 4, 8, 16, 32, 64 or 128. That value doubles in size from right to left. This is called the power of 2.
We also need to think about subnet masks. Previously I said, wherever there is 255, this is the network section and wherever there is a 0, this is the host section. That’s true in the simplest form, however, it can get a bit more complicated than that.
The real way to see which part of an IP address is the network section is by looking at the subnet mask binary bits and comparing it to the IP address binary bits. Anytime you see a 1 value, this bit is the network section and anytime you see a 0 it’s the host section.
Instead of the full subnet mask, you will often see it written as a forward slash, and then the number of network binary bits. For example, instead of 255.255.255.0, we could write it as /24. This is usually added to the end of the IP address.

IPv4 address exhaustion
IPv4 address exhaustion is the depletion of the pool of unallocated Internet Protocol Version 4 (IPv4) addresses, which has been anticipated since the late 1980s. This depletion is the reason for the development and deployment of its successor protocol, IPv6.
The IP address space is managed by the Internet Assigned Numbers Authority (IANA) globally, and by five regional Internet registries (RIR) responsible in their designated territories for assignment to end users and local Internet registries, such as Internet service providers. The top-level exhaustion occurred on 31 January 2011. Four of the five RIRs have exhausted allocation of all the blocks they have not reserved for IPv6 transition; this occurred on 15 April 2011 for the Asia-Pacific, on 14 September 2012 for Europe, on 10 June 2014 for Latin America and the Caribbean, and on 24 September 2015 for North America.
IPv4 provides approximately 4.3 billion addresses; a subset of these have been distributed by IANA to the RIRs in blocks of approximately 16.8 million addresses each. The depletion of the IPv4 allocation pool has been a concern since the late 1980s, when the Internet started to experience dramatic growth. The Internet Engineering Task Force (IETF) created the Routing and Addressing Group (ROAD) in November 1991 to respond to the scalability problem caused by the classful network allocation system in place at the time. The anticipated shortage has been the driving factor in creating and adopting several new technologies, including network address translation (NAT), Classless Inter-Domain Routing (CIDR) in 1993, and IPv6 in 1998. IPv6, the successor technology to IPv4 which was designed to address this problem, supports approximately 7038340000000000000♠3.4×1038 network addresses.
