If you are using ppp/pppd on your FreeBSD2.0, they will negotiate to
peer (Provider) for your and|or Peer IP address each other. In your
case, you just set up Provider IP address as permanent and your IP is
given by your Provider. The key is you just need your IP address and
Provider IP address as default route but not your name
(i.e. tama.spec.co.jp) on your side.

So doesn't matter not exist your IP address/IP name pair in these file.

On Provider side, ppp will assign your IP address as Dynamically and
Your IP name should be assined as *statically*. Otherwise they can't
provide a service indivually site/person....Addition, specifically
with NNTP, Only containing your IP name in nntp access file but not IP
address, right?

> Any insights ?

Ask the provider this point, if they can't resolve, I recommend you
should better choosing other provider...
