Changing DHCP Range Results in Error

Message 1 of 3
(998 Views)

I am trying to change my Fios-G1100 router's DHCP server to give out class a ipv4 addresses as opposed to the regular 192.168.1.x ones, so I changed the settings under My Network->Network Connections->Network (Home/Office)->Settings to look like this:

The problem is when I click apply, I get the following message:

"The number of IPv4 Addresses in the DHCP IPv4 address range must not be more than 256."

Is there some other setting I must change to have a wider class a ipv4 address range?

I am curious, though, why do you need more than a class C space?  Do you have more than 254 devices on your LAN?  Depending on your use case, you may need to setup your own DHCP server and maybe even a 2nd router.


Note that if you have Verizon set-top-boxes, they may not get along with a non-default DHCP configuration.  If you don't have them, you can replace the G1100 with any router you like.  That could be a solution for your use case.
