Important:This article applies only to local devices connected to your router (laptop, smartphone, tablet, and others.) These devices can have static IP addresses that only your router can detect. The outside world won’t find these IP addresses but your router can also have a static IP address that the rest of the internet detects. Learn about Static IP for your Wifi point’s WAN .
When you use DHCP IP reservation, your Wi-Fi network assigns the same IP address to a specific device whenever that device connects to your network.
Why use DHCP IP reservation or Static IP
Most devices use DHCP, which assigns dynamic IP addresses as default. But sometimes, you want devices to always have the same IP address, for example, a wireless printer. When you print something, your computer and printer locate each other through IP addresses. If your printer’s IP address keeps changing, your computer may not always be able to find it. When you provide your printer a static IP address, it ensures that your computer always knows where to locate your printer. Static IP address won’t change even if your device is rebooted or if a DHCP IP lease expires.
Tips:
- You'll need DHCP IP reservation, or Static IP for your client if you want to set up port forwarding to that device .
- You can customize the subnet you use under LAN settings if you prefer to use a different subnet.
