So recently I've come across an issue with a large ISP announcing a /22 and /25 of IPv6 space. We are currently filtering <28 and >48 which until now has worked fine for us.
What are others using as their prefix filters in the DFZ?
The NTT global backbone (AS 2914) generally accepts (barring the other filters) IPv6 prefixes within "2000::/3 ge 12 le 48" over eBGP. Longer prefixes are only accepted on customer sessions, when a valid IRR route6 object exists. Kind regards, Job
