It's definitely a long standing issue. While HE provides a fair amount of primary uplinks for me in various capacities, I often find myself needing to bring another blended provider into the mix just to cross the 'cogent bridge' so to speak. I run a fair bit of v6 only stuff these days, but only a small amount of traffic comes from that bridge area, so unless you're on cogent directly it's almost a non-issue.
While I can't really speak to cogent's motivations for not doing this, HE is more than happy and willing to, and they DO peer on v4, so it's definitely a .... interesting subject, to say the least. -----Original Message----- From: Randy Bush via NANOG <[email protected]> Sent: Thursday, January 15, 2026 6:28 PM To: Elmar K.

IPv6 has farther to go than we might like. randy _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/L5SRNW5S57YRLAGMTS4GSPA7LMGARCWG/ _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/5QB774UQ5K7CM7CZ3AO3HTKSX6AQ2GBR/
