I noticed on my mac the my local DNS server is set as the IP address of my router. Does this mean my ISP provided router is acting as a DNS server?

[@jatoxo]

Yes, it will probably just forward the request to the DNS server that you have specified in your routers settings

[@jawosammadennhier7062]

That is correct. The local DNS within the home internet router is a current feature of most current ISPs. It makes the administration of the local home network much easier than without.

[@jawosammadennhier7062]

@@jatoxo That is correct.
