It’s not something you need to do much, but it’s a good thing to check if you need to make a quick DNS change on a network which you aren’t very familiar with.
In DNS, go to View, Advanced. It will show a check beside it when advanced is enabled.
Now, go to forward lookup zones and find the record you intend to change, right-click and select Properties.
At the bottom, you’ll see Time to Live (TTL). The setting will likely be 1 hour.
Again, this isn’t something that often needs to be changed, but can be beneficial to review prior to making some important change.
