I liken it to the days when automobiles had carburetors; a mechanic could fix most engine performance problems by fiddling with the choke—spritz a little WD-40 into the throttle body, charge and retire in the suburbs after a few years. Check the TCP/IP settings, run a few utilities to verify the zone records, charge 0 (correcting for inflation) and retire to Arizona.
You’ll learn to identify the most common domain name system issues that cause problems for AD and Exchange and how to avoid them in the first place or isolate and resolve them if they occur in production.
Usually the update of PTR records is a manual process where the user of a given IP address must send a request to the organization that manages the IP network, to add/remove/modify the PTR record for a given address.
What we outline in this post is how you can create and update PTR records for yourself, without having to revert to us.
Reverse DNS (r DNS) is the inverse process of this: the resolution of an IP address to its designated domain name. One level below the arpa root are the delegated servers for IPv4 and ip6for IPv6.
This document explains how reverse DNS works and how to configure it for your zone. Further down the tree, there are delegations for the /8 blocks that IANA allocated to the RIRs, the allocations that the RIRs gave to the address holders, all the way down to the individual IP addresses and names that you have configured for your Internet-enabled hosts.
If you’re an experienced Windows system engineer, they may seem a little trivial.
