How Google apps domain is being set up for naked domain redirection?

  • 772

I've purchased a domain as part of google apps "standard" edition signup.

This is how the zone record was configured on godaddy:

; SOA Record
VEKSLERS.ORG.   3600    IN  SOA ns33.domaincontrol.com. dns.jomax.net. (
                2010091700

                604800
                86400
                )

; A Records
@   3600    IN  A   216.239.32.21
@   3600    IN  A   216.239.34.21
@   3600    IN  A   216.239.36.21
@   3600    IN  A   216.239.38.21

; CNAME Records

; SRV Records
_xmpp-server._tcp.@ 3600    IN  SRV 5   0   5269    xmpp-server.l.google.com
_xmpp-server._tcp.@ 3600    IN  SRV 20  0   5269    xmpp-server1.l.google.com

_jabber._tcp.@  3600    IN  SRV 20  0   5269    xmpp-server4.l.google.com

; NS Records
@   3600    IN  NS  ns33.domaincontrol.com
@   3600    IN  NS  ns34.domaincontrol.com

Now, I know that google app engine does not support "naked domains" and indeed a forwarding is configured from vekslers.org to www.vekslers.org.

What I don't understand is how this is being setup? Assuming that "@" in A records means "root" (?), these configured IP's lead to Google servers, does the AppEngine team have a default redirect from foo.com to www.foo.com is foo.com is a registered Google Apps domain?

Clarifications would be highly appreciated, thanks.

    Looks like it:

    $ host vekslers.org
vekslers.org has address 216.239.32.21

$ curl -D- VEKSLERS.ORG
HTTP/1.1 302 Found
Location: http://www.vekslers.org/
Date: Fri, 01 Oct 2010 14:27:22 GMT
Content-Type: text/html; charset=UTF-8
Server: ghs
Content-Length: 221

    216.239.32.21 is owned by google, so it looks like they are emitting the redirect to www.vekslers.org.

    When they say they do not handle "naked" domains I think they mean you cannot serve your site from a naked domain. Instead you have to let them redirect the naked address to the non-naked one as they are doing above.
