Re: IP addresses question

As IP address space is becoming quite scarce these days, we don't want to use registered addresses for the ISDN network (it doesn't have to be visible from the Internet).

We have three solutions : - use RFC1597 addresses, but there is no reverse DNS for such addresses (problem when doing a traceroute) - use some kind of unnumbered scheme, but it's difficult to manage on Cisco routers with multiple dial-in BRI. - use a registered addresses anyway ...

Any advice, experience ?

We use dynamic unnumbered links with a router from Securicor 3net (are you stuck with Cisco?) and it works *very* well. Cheers John
