Just some basic questions on DHCP

English Network/Internet

and I can’t find an answer after some looking.

This is theoretical but does a router need to have DHCP turned on in order to work properly ?

Consider the case where there are only 2 clients each has a static IP address:
10.0.0.1 and 10.0.0.2

Since they were not assigned by the router but need to be managed, does the router need to have DHCP turned on with a range restricted to only those 2 addresses ?

Could you assign a static address outside the range to a 3rd client ?

thanks

No… DHCP is just a way to give addresses. Once boxes have addresses,
however they get them as long as they are valid for the network
(ip/netmask/route configuration) everything else should just work.

Good luck.

Hi
No, you can disable dhcp if your running static ip’s. I have on my router I assign .230-.240 as dhcp then define my static ip addresses below this. Use the netmask to restrict even more, so you can still limit the total number of ip addresses.

DHCP only assigns addresses and network configurations so is not necessary.

If you configure static addresses manually, you only need to know the correct parameters of your network, eg

  • What is the permissible address range
  • Address and Subnet Mask
  • What is the Default Gateway
  • If name resolution is supported, configure the method or the location of the nameserver
