IPv6 - LogeshVel/learning_resources GitHub Wiki
Hexadecimal
For octal we need 3 bits to represent.
For Hexadecimal we need 4 bits to represent. (Each hexadecimal digit has four digits of information)
Why IPv6?
IPv6
Packet Format
Prefix
If the prefix is the multiple of 4 then its easy to calculate the network address and the host address.
But what if the prefix is not multiple of 4. Then we need to go for the binary calculation.
EUI
EUI is used to make the IPv6 host portion that will be attached to the provided IPv6 Prefix.
EUI is a method of anutomatically generating IPv6 address using a specific prefix and a MAC address
IPv6 Address types
Global Unicast address
Unique Local address
Link Local address
Multicast address
Anycast
Loopback address
Pcap
Solicited-Node Multicast Address
Neighbor Discovery Protocol - NDP
Neighbor Solicitation - NS
*In the Destination MAC it uses the Multicast MAC for the NS. Since IPv6 has no broadcast so NS uses the Multicast MAC address.
