We configure our DSL customers the same way you do. Static PVC, Static IP. Each user has a static IP and in 99% of the cases, we do not assign any dynamic IPs. However, I would say that it is safe to say that the majority of the ILECs here in the US provide DSL service where the IP is dynamic. Most of the time, it doesn't change, but it is very possible that the next time that the user logs in (most are also using PPPoE for the connection setup) that the DHCP server might give them another IP. As such, when we have seen our IP blocks get blocked strictly because of the rDNS entry having 'dsl' in it, a simple email to the admins explaining that we are not providing dynamic services has gotten our rDNS entries taken off of the blacklist. -Sean Sean P.
