Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Mon, 27 Jul 1998 09:52:57 +1000 Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG A reminder about updating DNS info - the NIC needs to know both the name and the IP address of your DNS servers so that (in the common case where the nameservers for foo.com live inside foo.com) the nameserver can return a so-called "glue record" with the IP address. Otherwise, when you ask "who is the domain server for foo.com" you get told "dns.foo.com" but you can't look up the address of dns.foo.com without knowing the answer to the question you are trying to ask in the first place! The upshot is changing _either_ the name or the IP address of a listed name server requires updates to the NIC database. So tricks with cnames etc don't actually add much flexibility.
