Appendix B - Networking Basics
Example: If the router´s LAN IP address is 192.168.0.1 or http://dlinkrouter.local., make your IP address 192.168.0.X where X is
a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set the Default Gateway
the same as the LAN IP address of your router (I.E. 192.168.0.1 or http://dlinkrouter.local.).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1 or http://dlinkrouter.local.). The Secondary DNS
is not needed or you may enter a DNS server from your ISP.
