Free IP Address Tracker from SolarWinds: "Does managing your IP address space with spreadsheets remind you of a visit to the dentist? Necessary, but usually painful? As if keeping the network running in tip-top condition wasn’t enough, you have to spend precious time wading through home-grown IP address tools to track down conflicting addresses and to see which ones are free. Well, no more – you can finally ditch your spreadsheet (and even start to enjoy IP address management)!"

Oversimplified DNS - Your Name Servers (NS records)
Oversimplified DNS - Your Name Servers (NS records): "BACKGROUND: Every domain name is required to have a primary nameserver (only one), and at least one secondary nameserver. This is to help ensure that all domains are reachable. For example, if you have 3 separate offices, and one of them suffers a disaster, that shouldn't prevent people from being able to reach the other two offices.
The WHOIS database lists all the authoritative nameservers (ones that get updated automatically when you make changes) for your domain. This list gets sent to the root server for your Top Level Domain (such as .com). Anyone in the world trying to reach your domain will get that list, and go to one of the nameservers to resolve a subdomain within your domain."
