I recently signed up for ACT and realized that they assign a private IP address and so having trouble getting OpenDNS to setup. Initially, I tried to add the public IP manually on OpenDNS and got an error that the network is already existing, which means that the public IP was added by another user to their account. After a few days I attempted to setup again and this time the public IP was different IP and it got added to my account. I could configure the filter level and after a few minutes I could test that it is working. However, I am concerned that the public IP would change silently again and then I may lose the ability to control the filtering.
I guess one solution is to pay Rs.250 per month extra to get a static IP assigned (which seems to be in the 124.xxx range) but before I go that route, I would like to make sure there isn't something I missed here. Will using PPPoE instead of DHCP help somehow?
