DNS
Also known as Domain Name System
The system that translates names like desertlakes.io into the IP addresses computers actually connect to.
Nearly every connection begins with a DNS lookup, which makes DNS both critical infrastructure and a useful control point. When DNS fails, everything appears to be down even though the network is fine.
It also holds records that determine whether your email is trusted, including SPF, DKIM, and DMARC. Domain registrar access is therefore a high-value credential worth protecting accordingly.
Where this comes up
DNS sits inside our networks and infrastructure work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
Measure this on your own domain
Our free email authentication checker reads this record for any domain over public DNS, grades what it finds, and gives you the exact record to publish if it is wrong. No sign-up.
