WebThe first two octets ( 16 16 bits) identifies a network administered by the Comcast (an Internet Service Provider). The last two octets (the final 16 16 bits) identifies a home computer on that Comcast network. An IP address identifies a network and then a node within that network. WebThe major difference in IPv4 and IPv6 packet formats are as follows: 1. IPv6 packet format does not contain header length field as IPv6 base header has fixed length of 40 bytes. IPv4 head is variable in length so header length field is required. 2. The header checksum field is not present in IPv6.

WebAn IPv6 address consists of sixteen octets, displayed in hexadecimal representation (two hexits per octet), using a colon character (:) after each pair of octets (16 bits are also known as hextet) for readability, such as 2001:0db8:0000:0000:0123:4567:89ab:cdef. [5] See also [ edit] Variable-width encoding Notes [ edit] WebA non-abbreviated IPv6 host address is shown here: 2001:0DB8:0001:0000:0000:0000:0000:0001 A hextet is the hexadecimal, IPv6 version of an IPv4 octet. An IPv4 address is 4 octets long, separated by dots. An IPv6 address is 8 hextets long, separated by colons. The IPv6 packet header has a minimum size of 40 octets (320 bits). Options are implemented as extensions. This provides the opportunity to extend the protocol in the future without affecting the core packet structure.
