IPv6 is mostly using SLAAC. SLAAC is 64 bit addressing architecture. (by the way, 64 bit is enough for addressing of everything) Even if somebody use DHCP, he typically makes subnet "SLAAC compatible", it means: use 64 bits for addressing. Where is the issue there? Unless the A-bit is set for the prefix in the RA, no machine will do autoconfiguration using SLAAC. -- kind regards Marco Send spam to abfall1762406841@stinkedores.dorfdsl.de _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/nanog@lists.nanog.org/message/H7IGODXA...
