OK.. let's say you're a DSL provider. Are you going to have your DHCP server populating the forward and reverse DNS? With what, the account holder's name? somename.example.com ?I'll suggest that (a) IF the addresses do migrate among different customers of the ISP, (b) the addresses handed out are publicly routable, AND (c) the CPE has to 'authenticate' itself to the head-end, then it is _very_ useful *to*the*ISP* to have dynamically-assigned DNS records of the form: cust.{accountid}.{locationid}.ISP.{com/net/TLD} or something of the sort. Something of that sort can save a -lot- of time/effort in identifying the customer involved in a complaint.
Surely that's only useful if they're still allocated the address at the time of investigating said complaint; a dynamically updating DNS record like this is really no substitution for accurate accounting records in your RADIUS system. Tom
