CloudVPS: update DNS record for eqiad1 egress (routing_source_ip) & ingress
Closed, ResolvedPublic

Description

This naming is probably not accurate:

$ host 185.15.56.1
1.56.15.185.in-addr.arpa domain name pointer internal-server-nat.wmflabs.org.

That IP is the one we use in the routing_source_ip setting.

Change 541526 had a related patch set uploaded (by Arturo Borrero Gonzalez; owner: Arturo Borrero Gonzalez):
[operations/dns@master] CloudVPS: use wikimediacloud.org domain for Neutron-related IP addresses

https://gerrit.wikimedia.org/r/541526

I'm proposing 2 changes:

  • the one in the patch: https://gerrit.wikimedia.org/r/541526
  • one in designate, in the wmflabsdotorg project, the record 1.56.15.185.in-addr.arpa. with id 1d828761-a55a-43dc-b1cd-2e99da4bc8b4 , from internal-server-nat.wmflabs.org. to nat.openstack.eqiad1.wikimediacloud.org..

Both changes go together.
