does it matter if a static LAN ip is included in a routers DHCP scope? lets say routers scope is 50-100 and my static LAN ip is in that range?

Thanks. We'll let you know when a new response is added.

If by static you mean you set the IP on your NIC, that is not a problem, no. You could also set a reservation as well. But that will not cause problems for you.

**************************
Having a static IP that is within DHCP range will cause you problems. It can also be tricky to find if you don’t know where to look when the address conflicts start poping up. <b>Know your networks DHCP range</b> and <b>keep your static IP’s outside of it</b>.

Most “smart” DHCP servers will do some type of test (ping) to confirm if an address is in use before handing it out. However, I do agree that a “static” address should have a reservation. The other option is creating exclusions in the DHCP scope for static addresses.

    If you are using the Static IP which is in the DHCP scope make sure you reserved this IP or else there can be an IP conflict. Cheers Yasir
