Quick Question on DHCP

Hi,

Can anyone advise me on the best practice when configuring DHCP? Basically if you wanted to set up a Vigor router with a static IP, you do the configuring in the web browser of it, but do you set an exclusion for it, or a reservation?

Is there a reason to use one and not the other?

Cheers

    I always exclude a block of addresses in my scope for static devices like servers and network equipment

    I do the same. I'll setup up an exclusion range. Let's say you have a 10.0.0.X network. I'd make an exclusion 10.0.0.1 - 10.0.0.20. Then you have 20 IP address to assign to your servers, switches, printers, print servers, gateway/firewall, Vigro router, ect...

    This also helps for troubleshooting too. Because you know what the IP address of your servers, or at least what range they are in.

    You can also just leave addresses off the pool. i.e. set your pool to be 51-254. Then you can have 50 (or however many) addresses to assign statically. That's what I do. I'm too lazy to use exclusions.

    You should also balance your pool between two servers for redundancy. MS recommends 80/20 split, but I believe most people do 60/40 or 50/50.

    Personally, I use the 100/0 split. :P
    All things are possible, only believe.

    I hardly ever split the range up at my clients. But then again I guess its hard to split it up,if they have only one server.
