:shrug: The last 3-4 "home" routers I've used here all allowed reservations outside the pool (Linksys, D-Link, Actiontec, Motorola). Here's what I can do with an Actiontec, e.g. As you can see, it's the DHCP server that's reserving the static IP for that MAC address, and it's outside the pool.
Well, that is a Verizon router you have there... As mentioned, if you assign an IP address via the router to an IP address outside the DHCP range, it is not a DHCP Reservation. It is just a reserved IP address. Except for the nuance of the name, there is really no difference in how it works.
In the DHCP Reservation, the DHCP server is assigning an IP address to the device with MAC specified and the IP address you requested. Whenever that DHCP lease expires, it is renewed with the same IP address. The DHCP server also knows not to use that IP address when
assigning IP addresses to other devices.
In a reserved IP address setting (outside the DHCP range), you are just telling the router to assign a specific IP address to a device according to its MAC address. In some cases, certain routers still require this assignment to be for an amount of time. When that time is up, the router will see if the reservation is still present at which time it "renews" the lease. Other routers allow a more permanent setup since it knows it will never use that IP address as it is outside the DHCP range.
