DNS is the first step in the process of reaching online assets. When coupled with intelligence about those destination endpoints and the network path between them, it can help get the right user to the right asset, improving performance, reachability of those assets, and security posture.

Dyn has been in the managed DNS business for over 10 years (and pioneered Dynamic DNS before that), so the DNS terms in this guide are commonly heard around the proverbial water coolers at Dyn, but we realise they can be a bit arcane despite the importance of DNS.

That’s why we’ve assembled this DNS Terminology Guide as your reference.
