説明

The current document on net.Resolver.LookupIP was not clear on the return values (i.e. what to expect when err is nil).

Looking into the source code, LookupIP uses internetAddrList here, and the comment for internetAddrList here does state the slice would contain at least one IP when err is nil.

We should duplicate the comment of internetAddrList to LookupIP.
