Subdomain not resolving to IP

Question

I created a subdomain http://themes.ibrogram.com and it doesn't seem to work, however http://ibrogram.com/themes does work.

I've had this issue for ages using an A record and can't seem to figure out how to fix it.

Any ideas?

Answer 1

You'll need to add a zone file entry with the following A record:

themes    3600    IN  A   199.38.116.24

You can verify that it resolves by typing

dig themes.ibrogram.com

Note that you still need to ensure that your web server is setup for named-based hosting. Assuming that it is Apache, it will be something like:

NameVirtualHost *:80

<VirtualHost *:80>
ServerName themes.ibrogram.com
DocumentRoot /path/to/themes
</VirtualHost>
