From the provider perspective, what is the prefix-length that most are accepting to be injected into your tables?? 2 or so years ago, I read where someone stated that they were told by ATT that they weren't planning on accepting anything smaller than a /32. So what if I get my shiny new /48 from ARIN and am already multi-homed??? Does ATT not want my business (which they wouldn't get if the first place, but for argument sake, yes, I chose to pick on ATT, sorry if I offended anyone :) I already see /40's /48's ,etc in the v6 table, so some folks are allowing /48 and smaller, so what is the new /24 in v6?
Generally, a /48 from PI space and a /32 from PA space will be accepted. If you were issued a /48 from ARIN it will generally be accepted. Some accept all the way out to a /64. I do see some de-aggregated /64 nets I am currently filtering but since the path is the same as the /32, I haven't seen need to open those filters up yet. Can't figure out why those are de-aggregated either as I don't see the more specific announced anywhere else.
