What is strange is that your router does not have a caching name server
that integrates with the DHCP server. This is a common and useful
feature. Not having it forces work-around's like putting LAN host IP's
into the /etc/hosts files of every other LAN host, which is a PITA to
maintain. Alternatively, implement your own integrated DHCP server and
caching DNS server.
Low-cost solutions include:
1. Router appliance -- re-flashing the firmware with a FOSS firmware
distribution like DD-WRT.
2. Home-brew router using a PC -- installing a second NIC and a Linux
or BSD router distribution like IPCop or pfSense.
I tried the former on an older Netgear device and it worked. But when I
later tried to flash an upgrade, I bricked it.
I ran home-brew PC routers for years. This approach gives you the most
control, and pfSense rocks. But, I burned up a lot of energy, made a
lot of noise, and generated a lot of heat. Unfortunately, ITX PC's with
dual NIC's are too expensive.
So, I researched commercial products, asked around on Linux and BSD
lists, and bought Ubiquiti Networks UniFi stuff:
https://www.ubnt.com/unifi-routing/usg/
https://www.ubnt.com/unifi/unifi-ap-ac-lite/
I run the UniFi SDN Controller server on Debian:
https://www.ubnt.com/download/unifi/
What do you mean by "The non-"computers" use the router's IP address for
their configuration"?
