Not sure whether I fully understand the question in all details, but: 1. on a LAN/WLAN (basically where NS/NA is required to work, = broadcast domain with MAC addresses), the use of a /64 prefix is recommended 2. Each host (being server or client) must have at least one global address within this prefix
If you have one server per LAN, then it is perfectly OK to use one /64 per server. If you think about that, currently you use a /32 for IPv4 address :-) You are currently wasting more space (4 billion times more) -éric From: Teerapatr Kittiratanachai <maillist...@gmail.com<mailto:maillist...@gmail.com>> Date: mercredi 18 juin 2014 05:28 To: "ipv6-ops@lists.cluenet.de<mailto:ipv6-ops@lists.cluenet.de>" <ipv6-ops@lists.cluenet.de<mailto:ipv6-ops@lists.cluenet.de>> Subject: IPv6 Assignment for Server Dear IPv6-Ops, I want the suggestion about the best practice for assign IPv6 Global Unicast address for server. According to the IPv6 Subnet ID also be built in with IPv6 address, so if I assign the /64 mask to the server is it will be some of wasteful usage? AFAIK, the /64 mask address can be brought to use for many other subnets. Is it more suitable to assign the /128 to the server, or end server that doesn't act as any other gateway. Thank you in advance. Regards, Teerapatr Kittiratanachai (Te)
