these are the instructions. how do i do this?

"DNS Instructions
You need to create a CNAME entry in your DNS tables. If your website is www.domainName then you want to create a CNAME for hostname.domainName to point to www.empirevstore.com. The syntax for this command is

store IN CNAME www.empirevstore.com.

Note the trailing period after empirevstore.com which is required to make this a fully qualified domain name.

After you make this change and restart your DNS service you should be able to test this with

nslookup hostname.domainName
A reference to www.empirevstore.com should appear. If you see a reference to www.empirevstore.com.domainName, then you need to examine your entry to make sure the trailing period is added as mentioned above."

anybody?
