[ipv6-wg] RIPE 80 IPv6 wg session Wilhelms DSL broke, some unanswered questions

as a developer I can say with some confidence, that a big hurdle is to
use hostname instead of IPs, it's way simpler to use IP during
development than to use hostname where you have to configure DNS
record to do so.

What happened to /etc/hosts files?



And this has the underlying problem in large development setups where
the single developer or the single developer group can not (due to
internal rules) simply change / configure DNS records.

It’s not uncommon for companies to exclude IPv6 from minimum viable product
as its “too hard”

help the deployment? It would help with some migrations from IPv4 to IPv6 I
think. (Mark Scholten / asking for myself)
