Domain Name System (DNS) is a method that involves naming network systems and computers in a manner that makes them easier to locate, track, and work with. Checking the DNS settings on your computer can be helpful if you want to find out specific DNS information about your network such as the IP address for your domain or server
The Domain Name System (DNS) is a system used to convert a name (like www.google.com) into an IP address (like 192.168.2.1) which is used by computers to communicate on a network such as the Internet.

In Cisco Prime IP Express 8.3 and later, both the Caching DNS and Authoritative DNS servers can run on the same operating system, without the need for two separate virtual or physical machines. For more information on DNS firewall, see Setting up Caching DNS and Authoritative DNS Server on Same Operating System So they got/grabbed the first 3 IP addresses 188.8.131.52 through .3 as DNS servers so there were multiple options in case one was down. John Orthoefer said they initially had issues with complaints that these DNS servers weren't geographically diverse enough, since they were on the same /24 block of addresses Since forward DNS maps a hostname to an IP address, rDNS (or Reverse DNS) indicates that we are mapping the IP address of a server back to a hostname. Using rDNS, the IP address is reversed and then the in-addr.arpa is added to the end. For example, if we use the IPv4 address of 184.108.40.206, using rDNS, it would become 220.127.116.11.in-addr. Dynamic DNS Services are used by small companies and individuals when they want to publish a service on the Internet, and that service is hosted within an internal or home network. Home networks typically uses a NAT router to connect to the internet which means that devices located on the internal network aren't accessible from the Internet Please note: As of Teamspeak 3.1 if you are using your own external domains you will need to make some DNS changes. For TSDNS to properly function with 3.1+ Teamspeak clients an SRV record is needed. Required settings for using our service are: Name: _tsdns._tcp Port: 41144 Host: ts3dns.com
