  2. Internet checksum - Wikipedia

    en.wikipedia.org/wiki/Internet_checksum

    The Internet checksum, [1] [2] also called the IPv4 header checksum is a checksum used in version 4 of the Internet Protocol (IPv4) to detect corruption in the header of IPv4 packets. It is carried in the IPv4 packet header, and represents the 16-bit result of the summation of the header words. [3] The IPv6 protocol does not use header checksums.

    en.wikipedia.org/wiki/Template:APHD

    Template {{APHD}} is used to create augmented packet header diagrams. Template parameters [Edit template data] Parameter Description Type Status table header 1 (start) Generates the header. Example start String suggested offset 1 (numerical) If this parameter is numerical then it is interpreted as the octet offset of this 4 octet-sized table row, which is displayed in the left header. The bit ...

  4. IP in IP - Wikipedia

    en.wikipedia.org/wiki/IP_in_IP

    This field indicates the transport layer protocol of the datagram following this header. The value is set to 4 for IP in IP. Not to be mistaken with value 4 in the Version field, which indicates IPv4. Header Checksum: 16 bits This field is the IP checksum of outer header. Source IP Address: 32 bits This field is the IP address of the encapsulator.

  5. IPv4 - Wikipedia

    The field is 13 bits wide, so the offset value ranges from 0 to 8191 (from (2 0 – 1) to (2 13 – 1)). Therefore, it allows a maximum fragment offset of (2 13 – 1) × 8 = 65,528 bytes, with the header length included (65,528 + 20 = 65,548 bytes), supporting fragmentation of packets exceeding the maximum IP length of 65,535 bytes.

  6. List of IP protocol numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_IP_protocol_numbers

    This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.

  7. List of IP version numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_IP_version_numbers

    Packets that hold Internet Protocol data carry a 4-bit IP version number as the first field of its header. [1] [2] Currently, only IPv4 and IPv6 packets are seen on the Internet, having IP version numbers 4 and 6, respectively.

  9. Checksum - Wikipedia

    en.wikipedia.org/wiki/Checksum

    The procedure which generates this checksum is called a checksum function or checksum algorithm. Depending on its design goals, a good checksum algorithm usually outputs a significantly different value, even for small changes made to the input. [ 2 ]
