DNS question

[Red Squirrel]

Say I got two records, one for domain1.com and one for domain2.com

Say I add an entry for sub.domain1.com pointing to 1.2.3.4

In the domain2.com record I want something.domain2.com to also point to 1.2.3.4. Rather then make it an A record, is there a way to point it to sub.domain1.com? That way if 1.2.3.4 changes I'll only have to change it in once place instead of two.

i think you can create a CNAME

Yeah tried that, does not seem to work. It seems valid as I don't get errors though.

I was doing it like this:

something.domain2.com IN CNAME sub.domain1.com

what happens when you ping something.domain2.com? it should resolve to sub.domain1.com

 

[Red Squirrel]

was not working but got it working now, suppose to add a period at the end. So it should look like this:

something.domain2.com IN CNAME sub.domain1.com.

This works.
