Static IP address changed to another static IP address. What needs to be changed?

My static IP was on Verizon's network, who are subletting their Fios lines to Frontier. Now I am given a new static IP from Frontier's data network. May I have a ballpark list of configurations to change to the new IP? It is like me to miss one thing and cause a problem. I have a LAMP with proftpd & ssh tunneling.

Solution 1:

Checklist:

• Firewall: if you've put a firewall rule in which denies all traffic which where not designated for your IP, you need to change that.
• Interfaces file: Change the static IP in /etc/network/interfaces. This file is re-read when the network connection is set up again.
• ProFTPd: the address on which ProFTPd is listening on
• Apache: the address on which Apache is listening on. Also check your virtual host settings like <VirtualHost 1.2.3.4> and NameVirtualHost 1.2.3.4.
• MySQL: check the address it's listening on. Usually, this is set to listen on all addresses.
• DNS: all records which point to your IP.

• To make sure you did not forget anything, search all files on your server for the old IP address using:

  sudo grep -HrnF '1.2.3.4' /
  

  This command shows every occurence of the IP address 1.2.3.4 as filename:line: line with 1.2.3.4.
