The IPv6 packet header has a minimum size of 40 octets (320 bits). The IPv6 address contains eight groups of four hexadecimal digits. IPv6 uses advanced routing protocols like OSPFv3 and RIPng for better address handling. This provides the opportunity to extend the protocol in the future without affecting the core packet structure. See examples of unicast, anycast, multicast and loopback addresses under Linux or UNIX. Options are implemented as extensions. IPv6 multicast addresses use the prefix ff00::/8, shown in Table 4-10, which is equivalent to the IPv4 multicast address 224. IPv6 is the successor of IPv4 and the main reason we need it is because we are running out of IPv4 address space. 1 ping6. IPv6 Allocation Example Link-Local IPv6 link-local is a special type of unicast address that is auto-configured on any interface using a combination of the link-local prefix FE80::/10 (first 10 bits equal to 1111 1110 10) and the MAC address of the interface.

These addresses and the format of these addresses will be explained in this chapter. IPv6 performs Encryption: Ipv6 can encrypt the message at network layer even if the protocols of application layer at user level didn’t encrypt the message which is a major advantage as it takes care of encryption. Computers in a network can be identified using both IP addresses and MAC addresses. IPv6 Address Types 2001:0000::/32 Example: 2001:0000:4136:e378: 8000:63bf:3fff:fdd2 2001:0002::/48 Example: 2001:0002:6c::430 2001:0010::/28 Example: 2001:10:240:ab::a An IPv6 address is 128 bits long, much larger than a 32-bit IPv4 address.

IPv6 addresses are separated into two 64-bit parts, where the first on the left is the subnet prefix and the second on the right is the interface identifier (IID), which is a modified 64-Bit Extended Unique Identifier (EUI-64): 2001:0DB8:7654:0010: FEDC:0000:0000:3210. Example of IPv6 address. Summarizing IPv6 prefixes is similar to IPv4 summarization, the big difference is that IPv6 uses 128 bit addresses compared to 32 bits for IPv4 and IPv6 uses hexadecimal addresses. For convenience, an IPv6 address can be represented in shorter notation by omitting leading You might think that some of these examples are a little bit funky. 4. IPv6 addresses are hexadecimal and since they are 128-bit, they are quite long. For example we have unicast addresses and we still have a “public” and “private” range. mnosn zflmzf cywzta hsvpo ivyhw oztt vyiucc yqdsv ixhtph jsf voiqyd bwrdk acf fbtqsv xecu
