Officially, ::ffff:x.x.x.x is the format for an IPv6-mapped IPv4 address - there are of course also a number of transition mechanisms, namely 6to4 and its relative, 6rd, which map an IPv4 address into a global IPv6 one for the purposes of providing IPv6 access over IPv4 by creating an IPv6 prefix that is derived from the IPv4 address it's ...
IPv6 subnetting a /64 - what will break, and how to work around it?
2015年8月18日 · In such a subnetting configuration you will break SLAAC, so you need a DHCPv6 server to respond on each segment and static IPv6 addresses configured on all devices without DHCPv6 support. Bridging. Bridging is the other alternative. It essentially means you don't subnet but run your entire LAN as a single IPv6 segment with a /64 prefix.
