Using Address Reservation
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the
same IP address each time it access the router’s DHCP server. Reserved IP addresses should be
assigned to servers that require permanent IP settings.
To reserve an IP address:
1. Click the Add button.
2. In the IP Address box, type the IP address to assign to the PC or server.
(choose an IP address from the router’s LAN subnet, such as 192.168.0.X)
3. Type the MAC Address of the PC or server.
(Tip: If the PC is already present on your network, you can copy its MAC address from the
Attached Devices menu and paste it here.)
4. Click Apply to enter the reserved address into the table.
Note: The reserved address will not be assigned until the next time the PC contacts the router's
DHCP server. Reboot the PC or access its IP configuration and force a DHCP release and renew.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address you want to edit or delete.
2. Click Edit or Delete.
Using a Dynamic DNS Service
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you will not know in advance what your
IP address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service, who will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x),
the dynamic DNS service will not work because private addresses will not be routed on
the Internet.
