Since about three weeks I’m using IPv6 on my client. Since then I’ve learned some basics, which I would like to share.
Some facts:
- 128-Bit long
- Written with hexadecimal characters
- Written in 16-Bit blocks (8 blocks, maximal 4 hexadecimal characters each)
- Blocks separated using colons (:)
- Double colon (::) means omitted blocks (replaced with 0)
- Networks are using CIDR-Notiation for the network mask (e.g. /48)
As loopback address there is one address reserved, the very first (means all bits 0 except the last one):
::1
