I am using NAMED andI have several domain names that all need to point to the same IP.
Should I want to change that IP among all the domains, I am looking for the most efficient way without editing every domain record.
should I assign an A record to one domain lets say:
hello.com IN A 10.0.0.1
and then CNAME the rest to it
welcome.com IN CNAME hello.com
I know this will cause dual lookups I believe. Is there a more efficient way?
