Router as DNS server

[bobm_10]

On my home network which is behind a simple Netgear router, ipconfig shows my router as the dns server. Question, does my router simply pass the DNS requests along to the ISP's DNS server or does it maintain a cache of some sort. Thanks Bob

from my experience, when doing this with consumer routers, it is just acting as a forwarder for the request, and no caching is involved.
that's not say that it isn't, but it probably isn't.

on some routers it does cache DNS request. RouterOS is an example.
