Providers don't give out publicly routable /126. Generally most providers aren't going to give out anything longer than a /64 partially because they don't need to and partially because routing tables [0]. They want to route to you via a prefix that's pre-allocated to carve up for the region you're in.

- kitteh 7y agoA /48 is the minimum folks will pass via bgp on the internets (it's the /24 of the ipv6 world). Also another fyi: if you're rolling commodity hw (bcm tridents etc) after a /64 up to /128 you are dipping into another constrained forwarding table - can't fill your box with too many of those.
