we assign /112 per "end user vlan (or server)" at this moment... works
perfectly fine (and thats even "a bit too big").
- nobody wants to use dynamic ips on -servers- or -router links- anyway
i -really- can't see why people don't just use subnets with just the
required number of addresses.
Stateless autoconfiguration (which is NOT dynamic IP addresses; the IP
address is static but tied to the ethernet card) does not work unless
the subnet mask is exactly /64.
Even on a server lan you'll occasionally want to plug in a PC for
diagnostics without having to poke in an IP address by hand.
There are some great reasons to use a /112s or even smaller blocks for
some applications. Use them that way, sure. But IMHO it's
short-sighted to _assign_ address blocks at that size -- it means the
person downstream has to come back to you and waste your time when
they want to do anything else. And your choice delays them and wastes
their time as well -- a fine "customer service" indeed.
