Incorrect Answer Here hello.com does not have a trailing dot, and is likely to be rewritten as hello.com.hello.com., which would be incorrect.
Close
Incorrect Answer The trailing dot at the end of a hostname stops the origin name being added to the names. We really need ns1.hello.com to be ns1.hello.com. and not ns1.hello.com.hello.com., so the trailing dots are needed here.
Close
