Subject: InspSocket no longer resolves hosts. InspSocket::DoResolve() and the
 stuff that calls it is gone, if you pass InspSocket an invalid ip, it will
 bail during its connect. You must now use Resolver classes to resolve
 hostnames into IP addresses, if you wish to do this. Currently, only one
 non-extra module does this, see class ServernameResolver within
 m_spanningtree
