Which is exactly why hardcoding pool.ntp.org _is_ allowable, in my
opinion - and in fact indicated in such a case as this. Exactly because
(as I suspect you meant) it is not a fixed site, but a symbolic name
that translates to some reasonable site that is available now.

Incidentally, to the OP, it's not a URL. It is a DNS name.
