Charging for IPs

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... ----- Mike Hammett FD-IX https://fd-ix.com/ DNA Communications https://www.dnacom.com/
