Trouble directing A name and subdomain to different hosts

Jacob Lyles asked:

I am hosting a domain on namecheap with namecheap’s DNS service.

I want to point digest.politihacks.com to politihacks.wordpress.com with a CNAME record. This works fine.

However, I also want to point the top level name politihacks.com to github’s static page hosting service at 204.232.175.78. When I add the A record for this, it works as expected BUT the previous CNAME now also redirects to github instead of wordpress.

In my terminal I typed dig digest.politihacks.com and it looks like it SHOULD point to wordpress:

 ; <<>> DiG 9.7.6-P1 <<>> digest.politihacks.com

But as I mentioned, visiting digest.politihacks.com in my browser redirects to my github static page. What could be wrong?

Thanks!

My answer:


You set everything up correctly (except for politihacks.com having no A record at the moment).

The 301 redirect from digest.politihacks.com to politihacks.com is coming from the wordpress.com service. You will need to contact them to have this corrected.
