Description

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.

Contributor guide

Research direction
Locate the LookupIP function in src/net/lookup.go and add the comment from internetAddrList in src/net/ipsock.go to clarify that the returned slice contains at least one IP when err is nil.
