Running DNS locally for home network - Super User
https://superuser.com/questions/4578924.09.2009 · In the usual situation of home routers you just need to simply tell the router that the DNS server is 192.168.1.101 and reboot. If you can get a local DNS running on your broadband router, great, but a DNS server might benefit from lots of RAM for caching queries, depending on which DNS software you use. On my network I just use straight BIND.
