IPv6 fixes many problems in IPv4, such as the limited number of available IPv4 addresses. WebApr 9, 2024 · The IPv6 header is a streamlined version of the IPv4 header. It provides new features while retaining the core concepts that made IPv4 popular. It eliminates the fields that are rarely used, improves the remaining fields, and adds an additional field to provide better support for real-time traffic.

WebThere are two types of headers for IPv6. Fixed Header The fixed header starts an IPv6 packet and has a size of 40 octets (320 bits). Version (4 bits): The constant 6 (bit sequence 0110). Traffic class (6+2 bits): The 6 most significant bits hold the differentiated services (DS) field used to classify packets; The other 2 bits are used for ECN. Webstruct ipv6_header { unsigned int version : 4, traffic_class : 8, flow_label : 20; uint16_t length; uint8_t next_header; uint8_t hop_limit; struct in6_addr src; struct in6_addr dst; }; It's no different than how the header-struct was made for IPv4 in your example.

An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.

Fixed header format Offsets Octet 0 1 2 3 Octet Bit 0 1 2 3 4 5 … See more Unlike in IPv4, IPv6 routers never fragment IPv6 packets. Packets exceeding the size of the maximum transmission unit (MTU) of the destination link are dropped and this condition is signaled … See more Extension headers carry optional internet layer information and are placed between the fixed header and the upper-layer protocol header. … See more The fixed and optional IPv6 headers are followed by the upper-layer payload, the data provided by the transport layer, for example a See more On the Internet, data is transmitted in the form of network packets. IPv6 specifies a new packet format, designed to minimize packet header processing by routers. Because the headers of IPv4 packets and IPv6 packets are significantly different, the two protocols are not interoperable.
