Hi all, What IPv6 prefix lengths are people accepting in BGP from peers/customers? My employer just got a /48 allocation from ARIN, and we're trying to figure out how to support multiple end sites out of this (probably around 10). I was thinking about assigning a /56 per site, but looking at the BGP table stats on potaroo.net [1], it looks like this is not too common (only .29% of prefixes). Thoughts?
Traditionally, /48s are per-site. You should get a /48 for each site, in reality something like a /44 will do nicely giving you two additional /48 for growth. William
