Well, you *can* have the dhcp client on FreeBSD send an identifier, and with that identifier the dhcp server can assign the client a static ip lease. If that static ip is registered in your local dns, you're all set. Doesn't work well if you use the client on another network who doesn't offer static ip's. YMMV. > The following will be a possble workaround, but I'm wondering there can > be a smart answer in FreeBSD itself. > > It is possible to resolve the hostname corresponding to a dhcp-delivered > ip-address with a local name server.
