Of course, if there is another server handling DNS on the network -- use that IP address instead!! But, I use and recommend 127.0.0.1 instead of the actual IP of the NIC when there's only one server and it's a DC of the forest. I've had my Server2003's going for almost 2 years now with no DNS issues using 127.0.0.1

Is anyone aware of a public wildcard domain name that resolves to IP address 127.0.0.1. For example if I wanted to test a URL locally such as mywebsite.localhost.com or example.localhost.com but I don't have control of DNS settings (hosts file or whatever) then I would use this public DNS to resolve to 127.0.0.1.

I've had my Server2003's going for almost 2 years now with no DNS issues using 127.0.0.1 # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost 127.0.0.1 localhost. bazanovv May 26, 2016 6:25 AM pretty clear that the 127.0.0.1 entry in /etc/hosts is unfortunately not used. localhost and 127.0.0.1 are part of the loopback interface (lo0) and a lookup from /etc/hosts should suffice! no reason at all to query a DNS service unless explicitly specified.

I was concerned that because I had changed things around when setting up the pihole, that I had set it to 127.0.0.1, and I had failed to reset it back correctly.

The XSS vector is something I'd never thought of, but it is something of concern: having a localhost entry in your public DNS means any hacked machine could be "in your domain" (by running a webserver on 127.0.0.1) and potentially do all sorts of nasty things. Probably a good enough reason to get rid of the entry.

Sep 14, 2018 · As you can see, 192.168.8.1 is the DNS address as per the above output. Method 3: Using Linux Commands. In Linux distributions, DNS details can be extracted from 'host' or 'dig' commands. host : host command is a utility that performs DNS lookups. Therefore DNS server details can be viewed as below by using it.

The DNS server address on the client changes to something unexpected by the software or 3G/4G HotSpots, and they change the DNS setting back to the previous setting. The Umbrella roaming client then performs the same operation and changes any DNS servers back to 127.0.0.1.

In practice, localhost is treated as synonymous with 127.0.0.1 for usage and discussion. However, it’s important to remember that they are not strictly identical. Before making a DNS request to translate the text string typed by the user into a navigable IP address, the operating system checks the HOSTS file for any aliases or redirect rules.
