My company owns a Class C network we pay for 1200 a year for, which I believe is directly to ARIN. Right now our ISP is Level 3 communications, but we would like to get away from them. Our information is on the WhoIs info so I believe that means we can take it with us.
I would like to know what exactly we need to do to get traffic to route through the new ISP so that when we pull the plug on Level 3 we will still be reachable. Can I simply enable RIP or OSPRF on our router to advertise the network to the new ISP? Or do I need to update some routing information with ARIN?
Also, given that Level 3 owns 184.108.40.206 - 220.127.116.11, is that going to give us any problems taking a "reassigned" network with us?
