[Pdns-users] Geo DNS - Apex Alias (not resolving)

[Brian Candler]

$ dig +short @dns0.hotchilli.uk. geo.hotchilli.co.uk. a
46.17.220.152
$ dig +short @dns0.hotchilli.uk. hotchilli.co.uk. a
10.0.2.18

I see that's the response you configured for "unknown.geo.hotchilli.co.uk"

I'd be inclined to use tcpdump to look at queries from dist to auth, 
auth to recursor, and recursor to auth - and check the flow of packets 
when you send an external query for "hotchilli.co.uk". My guess is that 
the source subnet of the original query isn't propagating all the way 
through, and maybe you can identify at which step it's lost.

I do wonder if there's a better way; perhaps dnsdist itself could map 
hotchilli.co.uk to geo.hotchilli.co.uk? But I don't use dnsdist myself.
