Never mind the knowledge gaps in supporting and managing this, systems updates to handle this, educating customers on how to deploy, etc. I have never heard of something like this being deployed on IP circuits. From a configuration standpoint, without testing it, is it as easy as configuring an IPV6 BGP neighbor with an IPV4 unicast AFI/SAFI? And the received routes appear in the table with an IPV6 NH? -Brian On 2026-09-04 12:23, Owen DeLong via NANOG wrote:
This will only increase as IPv4 becomes more and more stupid.
I would approach any provider that did so asking if we can simply transit our IPv4 routing process over v6 addresses. This is viable on virtually every common routing platform today.

Cogent?

Has anyone else experienced an upstream provider that wants to charge you for the IPs you need to establish BGP sessions?
I understand charging for large blocks, but I literally just got a quote for two /31s. I have an existing contract elsewhere with them, and they gave me 3x /29s gratis (for three different ASNs, sets of BGP sessions, ec.). Now they're charging for each IP.
I thought charging for BGP sessions was ridiculous, but now for individual IPs to use those BGP sessions...
