Anurag Bhatia
After recieving lots of emails regarding SRV records issue in Google Apps I must say that Google has missing info in their documentation about SRV records. As per refering to official Google’s help here. It has missing info. about the location servers. Here are those missing SRV records… client._tcp.YOURDOMAIN.TLD. IN SRV 5 0 5222 talk.l.google.com. _xmpp-client._tcp.YOURDOMAIN.TLD. IN SRV 20 0 5222 talk1.l.google.com. _xmpp-client._tcp.YOURDOMAIN.TLD. IN SRV 20 0 5222 talk2.l.google.com. _xmpp-client._tcp.YOURDOMAIN.TLD. IN SRV 20 0 5222 talk3.

Glue Records

Anurag Bhatia
Glue records These are the mosy fundamental DNS record which actually start with the lookup. Let’s understand how to come in basic scenario…… Observe two sites - harisri.in & anuragbhatia.com There’s a basic difference in terms of DNS in both sites. Nameservers of harisri.in are ns1.anuragbhatia.com & ns2.anuragbhatia.com which belongs to a totaly seprate zone, but nameservers for anuragbhatia.com are ns1.anuragbhatia.com, ns2.anuragbhatia.com & so….. i.e domain is having nameservers which are sub zones of domain itself.

Most of web host state that if you have changed your domain’s name server’s to there’s server then also it will take around 24-48 hours for DNS changes to propagate. That’s not completely true.

Still that’s just a bit of “truth!” What I mean to say it’s just creates a wrong image of DNS working in eyes of a newbie.
