Adding ISP DNS Server to Root Hints RRS feed

  • Question

  • I've seen much discussion about DNS forwarding vs. root hints and wonder if there is a problem with not using forwarders and adding my ISP DNS Server to the root hints list.  Some say that using forwarders to your ISP is fewer hops and therefor faster.  Why not just add it to the root hints list?

    Root hints could resolve forwarders address, when you configure a forwarder, DNS will send forwarder address to DNS server of forwarder, and if DNS server of forwarder could not resolve address of forwarder, local DNS server will send address of forwarder to root hints.

    Root hints did not perform operation like forwarder.

    You could reference the article below for further understanding:
