If you sign up for static IPs, we will assign addresses to you when your service is installed and activated. The number of static IPs available is shown on the screen when you sign up for service. When you sign up for Google Fiber for small business, you can choose to have no static IPs (that is, dynamic IPs for all your devices), one static IP, or multiple static IPs. Your device keeps the same IP address until you cancel the reservation or remove the device from your network, even if the device is disconnected. Use advanced settings to reserve an IP address for a device on your local network. You can choose the Dynamic DNS provider and don't have to install additional software on your computer. When your IP address changes, the DNS entry for your server is automatically updated with its new IP address, so outside users can use the same domain name. Use advanced settings for your network to configure dynamic DNS. A static IP address is not required if you are hosting a server, although it can simplify the setup process. One example is VPN or other remote access solutions that trust (whitelists) certain IPs for security purposes. Static IP addresses normally matter more when external devices or websites need to remember your IP address. Most users don't need static IP addresses. Most devices use dynamic IP addresses, which are assigned by the network when they connect and change over time. When a device is assigned a static IP address, the address does not change. What is the difference between a dynamic and static IP address? Your browser then connects to that IP address. DNS would return the IP address assigned to Google’s domain name ( 74.125.239.35). For example, if you type into your browser, your browser would ask DNS for Google’s IP address. When you type a URL into your browser, your browser looks up that domain name in DNS. You can think of DNS as an Internet address book, mapping domain names to IP addresses. The Internet uses DNS (Domain Name System) to enable people to use words instead of numbers for Internet addresses. Network devices use IP addresses to communicate with each other. Just as a street address determines where a letter should be delivered, an IP address identifies computers on the Internet. An Internet Protocol (IP) address is a unique number assigned to every device on a network.
