But what impact might it have on individual services, organizations, and other smaller entities? Since the Internet is still IPv4 omni-present, and only partially IPv6, it probably doesn't matter at all to most. It might be much more important for diagnostic and measurement services like DNSviz though. At the moment, if you run IPv6 DNS servers on networks that are singly connected to Cogent, it will probably incorrectly flag those servers as unavailable. For such services, perhaps it would be better if they were not single-homed to either Cogent or HE. (To be clear, I'm happy that DNSviz is housed at OARC. So, I guess I might be suggesting that the community might consider how to fund a second ISP connection for OARC). -- Shumon Huque
