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 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 www.socl.in www.socl.in – 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
