Host www.xyz.in not found: 3(NXDOMAIN)

Question

I have a domain purchased from name.com - I am using heroku for hosting a rails app for this domain. Today I tried to setup DNS for this domain. The top level domain works fine but when I try to setup CNAME for "www", I get the following error :

ubuntu:~/rails_projects/socal$ host www.xyz.in
Host www.xyz.in not found: 3(NXDOMAIN)
('xyz' is just for example)

My CNAME settings in name.com looks like :

Record Type     Record Host     Record Answer          TTL  
CNAME           www.xyz.in      proxy.heroku.com       1800

This is as per the instructions on heroku.com-http://devcenter.heroku.com/articles/custom- domains Not sure what could be wrong with my DNS settings

I suggest reading this article that explain why it's so important to avoid an A record on Heroku.

I highly suggest using a A record for www ,as a Cname will cause 2 lookups at the server doubling the load. Cnames were designed fir when you don't control the other domain, An A record is much more suited for this

I cant create www A record with proxy.heroku.com - I get 'Invalid character used for record answer' I will try creating with ip – user70692 Feb 14 '11 at 13:14
Created A record for all heroku ips - still same error : www.socl.in 174.129.212.2 www.socl.in 75.101.145.87 www.socl.in 75.101.163.44 – user70692 Feb 14 '11 at 13:17
any time lag before the changes are reflected ? – user70692 Feb 14 '11 at 13:38
If you setup another record it should ask the server as it hasn't cached it yet. – Jacob Feb 14 '11 at 13:39
does heroku assign you a IP or a hostname? – Jacob Feb 14 '11 at 13:41
Heroku suggests 'proxy.heroku.com' for creating CNAME for www - and gives 3 ips to create A record for top level domain. I tried using hostname 'proxy.heroku.com' it throws error - invalid character used for record answer – user70692 Feb 14 '11 at 13:51
Sorry a Cname is correct in this situation what you need to do is check to see if you set your domains in heroku ssh like in the instructions. Your DNS record is www.mydomain.com. Cname proxy.herkou.com – Jacob Feb 14 '11 at 14:05
Holy ! - I did not put a "." after 'proxy.heroku.com' – user70692 Feb 14 '11 at 14:09
still same error though ! – user70692 Feb 14 '11 at 14:11

Your domainname – Jacob Feb 14 '11 at 14:19
