  1. Sam@!

    could you use an "Alias" record to host an xmpp server, or does it require an "A" record?

  2. moparisthebest

    Sam@!: You mean cname ?

  3. Sam@!

    no not cname although I'd be curious about that as well

  4. Sam@!

    my registrar provides a DNS record called ALIAS that seems to work with my DDNS, but I'm not sure if it would be compatible with xmpp (prosody) as it's not an A record

  5. Sam@!

    Actually in the end it would be a combination of one ALIAS record and multiple cname records

  6. moparisthebest

    As far as I know ALIAS isn't actually a DNS record type, sounds like something your DNS provider made up

  7. moparisthebest

    As long as underneath it uses cname/a/aaaa should be fine

  8. Sam@!

    >As long as underneath it uses cname/a/aaaa should be fine That's the hope. I'll test it out with another domain. thanks for the input!

    Sam@!, CNAME is not valid as a target of SRV, keep that in mind. otherwise you should be good to go.

  10. jonas’

    (even if ALIAS resolves to CNAME, that's not allowed as SRV target)

  11. jonas’

    (but ALIAS seems to resolve to A/AAAA always)

  12. jonas’

    (if I'm reading stuff correctly)

  13. Zash

    ALIAS seems to be something supported in some DNS servers where it's like a CNAME but it's resolved on the server instead of by the resolver.

  14. sam

    My SRV records point to my domain root, which is being treated as an A record, so I *think* SRV should be fine. Does that sound right?

  15. Zash

    Sounds fine.

  16. sam

    Cool, thanks for the help in here. o/

  17. Zash

    I note that if you use `_xmpp-client._tcp.YOUR-DOMAIN.EXAMPLE IN SRV 0 0 5222 YOUR-DOMAIN.EXAMPLE` (i.e. the default ports) then the SRV record isn't strictly needed, as the fallback is to behave as if it looked just like this in the absence of SRV records. That said, explicit > implicit.
