Validate existing link destinations

[WyrdByWord]

Apologies if I missed anything, since this seems like it would be a common need: is there a plugin or tool for validating existing destination/original links?

Thanks, but I had checked there before asking the question. I see a plugin that validates a URL when submitted, but I don't see anything that will check the existing destinations and note any that are 404 or otherwise unreachable. Sorry if I am just overlooking it.
