For a more profound understanding let’s break down the previously mentioned DNS components that are relevant to the DNS lookup process.Authoritative DNS Server An authoritative name server is a DNS server that stores DNS records (A, CNAME, MX, TXT, etc.) for domain names.The Recursive DNS server accesses the A record for the authoritative name servers and stores the record in its local DNS cache.

If you need to continue the use of HTTP, we strongly recommend utilizing your update client key instead of your account password.

"I want to send updates myself via TSIG rather than install software." Many hardware devices, such as DVRs, webcams, routers, etc, have built in update clients.

A conversion happens between 172.2, an IP, which designated to a device on the Internet.

This conversion is a DNS query, an integral part of devices connecting with each other to communicate over the internet.

An update client is a computer application or a feature in your router that keeps your hostname’s IP address up-to-date.

The update client periodically checks your network’s IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your Dyn account.

These authoritative name servers are responsible for storing DNS records for their respective domain names.

Step 4: Access the DNS Record For our example, to find out the IP address for we will query the authoritative name server for the address record (A record).

We recommend you use one of the official Dyn Updater Clients.
