Known as the largest internet and cable provider in the United States, Xfinity has successfully gained over 26 million cable subscribers and 32 million internet subscribers throughout the country. They were able to successfully do this through reliable, steady, and fast internet and other innovations that they have introduced to the public in terms of entertainment and connectivity.

Static IP on Xfinity residential gateway

A Static IP or static IP address is the unique and universal address of a network that doesn’t change. If you avail of Xfinity’s services or connect to their internet, you will automatically have a static IP that helps them identify you as their user, allowing you to send and receive data. 

Your static IP also helps save information about you such as your location, the websites that you frequently visit, stay logged into those websites, and do all other things that you do on the internet while you are connected to it. 

Now when you pay for Xfinity’s services, you are given your own residential gateway, which comes in the form of a modem and router. This device serves as a bridge where you would connect the rest of your gadgets (mobile phones, computers, smart devices) to gain access to the internet and even connect those gadgets to each other. 

It sounds pretty cool, isn’t it? Having your own static IP address that is solely dedicated to you, and this residential gateway could help you connect all of your gadgets to the internet.
