DHCD / IP Addresses

[dragonlight]

I have a DI 604 router, I have assigned all my computers their own IP addresses and so on. Would I or could I disable DHCP in the router? Looking for some networking tips.
Thanks Chad

If you manually enter all the addresses, it probably doesn't matter much one way or ther other.

I guess I'm curious as to why you go to the trouble to manually assign them, I'm lazy and let them be assigned for me.

I manually assign them, cuz I have 4 computer with remote desktop, and remote cams, and the router for some reason likes to switch the ip addresses sometimes.
I have to have stable ip addresses.

That's one of the reasons I like to use static IP address. Being able to remotely access computers is such an efficient way to set up a network. My customers just love the quick response. Some days I don't even have to leave home and get a decent amount of work done. Cause it's so fast and saves so much driving time, I get lots of time to play. It is also not that hard to keep track of. I just have a spreadsheet on each site's server with the assigned IP addresses. Also like to keep a post-it taped to each computer with the name and IP address (just in case of a reinstall). In the scheme of things this is not that much more to do.

One reason you might want to leave DHCP in place is just in case you occasionally get roving people coming in with laptops that might want to use the network for Internet access. If so then just make sure that the DHCP range is outside of the ones you use for your static IP addresses. Otherwise you can probably just turn it off.

That is just it, I don't want anyone comming in and plugging in, I would like to keep this netowrk tight. and I love the remote desktop, they have 5 computers here and I can access them all from where I live. I am about 5 hours away..and when they have problems I just pop in and fix them.

Just offering it as a possibility but not a necessity. Everyone's situation is different. If you will never need DHCP then there is no reason for leaving it turned on.

Thanks for all the help....

Many routers, like my D-Link DI-614+, allow you to reserve DHCP slots locked to MAC addresses. This allows my permanent network residents to have fixed IP addresses, and other machines that don't always get plugged in to have DCHP assigned addresses. The beauty of this scheme is that all of the machines are setup the same way, automatic IP addresses, so reconfiguration is very easy.

From the information provided by dragonlight in a previous post, he does not what anyone to be able to just plug into his network and get an IP address assigned. I'm also not sure why it is so difficult to just assign IP addresses to computers. You certainly don't need to worry about what MAC address each one would have and then configure anything on the router. It is also a solution that would work regardless of the capabilities of any router.

 

[JohnWill]

Who said it was difficult? However, it's certainly easier to just plug in a machine and have it connected.

Using DHCP all depends on your requirements. From a previous post from the original person "I don't want anyone comming in and plugging in, I would like to keep this netowrk tight"
