If you are using TXT records like "029845yn0sidng0345randomnyosndgf03548yn" then how do you know which one to delete once you are not using that service? Do you just go back and forth between different services to find the one (some services only show this while you are in a validation phase, so finding them later might be a pain), or do you just leave them around?

Ops guy... These days cloudflare allows you to put comments directly into their service, but for a long time I would just export the zonefile and annotate that. There is a KB article somewhere in jira that will tell you what stuff is. I can also summon the ticket history to see what changes were made and why.

Those comments have a very short length limit (smaller than the records themselves) and I don't understand why.

Simple, indirection to the rescue again! Just add an increasing number in the comment field and keep track of which number is which comment in an Excel sheet on SharePoint or similar.

And yes, I'm mostly joking.

Hopefully you're managing DNS as code, so you have a repo commit log that can give you that context.

Keep a log of every record added and why it was added. When making any DNS changes review the log as well.
