Localhost requests?

[jamie.andry]

Looking through my OpenDNS statistics, it appears my network is sending out a decent amount of traffic to resolve the domain 'localhost'.  Should I be concerned?

It means something on your network is trying to resolve that name via DNS, which it shouldn't be doing since localhost is the device itself.

It may or may not be an indication of a problem, but if you are concerned by it you should find out which device (or devices) is responsible for these DNS requests

You have configured the OpenDNS resolver addresses on the LAN/DHCP side of your router or on the end user device, causing that also internal name resolution requests go to OpenDNS.  This is totally normal in this case.

If you don't want this, configure the OpenDNS addresses only on the WAN side of your router if you can.

Sometimes also DNS servers return the right response on such a DNS request, see here my internal AD DNS server:

nslookup localhost.
Server:  dns1.local.prv
Address:  10.165.161.45

Non-authoritative answer:
Name:    localhost
Address:  127.0.0.1
