Step #4: In order to find the recipient's server, the sender's SMTP server has to communicate with the DNS, or Domain Name Server. The DNS takes the recipient's email domain name and translates it into an IP address. The sender's SMTP server cannot route an email properly with a domain name alone; an IP address is a unique number that is assigned to every computer that is connected to the Internet.
Each router has 2 IP addresses: an internal IP address and an external IP address. Your router's internal IP address is what you use to talk to your router. Use this IP address to login to your router and configure it for things like port forwarding. Your router's external IP address is what the rest of the world uses to find you on the Internet. Tell this IP address to people who are trying to connect to you if you are hosting a game or other kind of server.
