First let me apologize for my lack of knowledge in this area, but I'm not sure where else to ask this. I'm getting rid of all 20 IP addresses on my server and trading them for new ones. (The existing 20 are from my old host who had spam problems and got my IP's blacklisted with several BLS lists). I'm told that in order to avoid extensive downtime that I should lower the TTL on my server before we replace the IP's, but I have no idea how to do this. Can someone please point me in the right direction? Thank you very much in advance for any help, it is very much appreciated by this "command line dummy who relies on point & click" over here.
