Can you get a static ip address from dhcp?

[AmigaMan]

It seems that my laptop at work always gets a different IP address from DNS almost everyday now. I know dhcp means dynamic host configuration protocol and that it's supposed to give you a different ip address, but I'd like to know if there is a way to not have that happen. Can't you configure the dhcp server to always send out the same ip to a given mac address?

The reason I ask is I have several configuration files that have ip addresses hardcoded in them and I have to change them each time my ip changes. I'm getting tired of it....any suggestions?

You may end up with conflicts if you use a static IP in a dynamic range.

Why would you hardcode IPs in a configuration file? Can't edit the host file or DNS?

Sure, this is done all the time if your putting up a box that needs a static address. You can add an Address Reservation by the Laptops MAC address. This way the laptop's NIC will have a specific IP reserved.

What I did at home for my network was to have the DHCP server issues IPs from 192.168.1.5 thru .50 and set my own 5 server machines with static addresses starting at .50 and working backward, so .49, .48, etc.

That way any machine being added to the network, like friends dropping over for a LAN party are going to be assigned IPs at the beginning of the range, so no conflict. Long before I could ever worry about IP conflicts, I'd be tripping breakers(since I'm not doing any wireless).

ok, I'm an idiot...this is what LOCALHOST is for. duh.
I just set my config files to use localhost and it's working...

You can set up your DHCP server to reserve certain IP's for certain MAC addresses.

That's correct. It takes Admin access to do this though...
