That's an ambiguous sentence; did you mean that you always want to give out
the addresses in the *same* order, regardless of whether the client is token
ring or ethernet, or did you mean that token ring clients should get the token
ring address first, and ethernet clients should get the ethernet address
first? Your sentence can be read either way.

In the former case (always give out the addresses in the same order), use the
"rrset-order" option.

In the latter case (change the order depending on the client), use the
"sortlist" option.

You'll need to be running a fairly late version of BIND 8 (8.2. or later), or
BIND 9, in order to successfully configure either of these.
