Except it really isn’t? I mean, this is pretty basic for a regex:
(events|notify|pipe|settings|telemetry|urs|vortex(\-win)?|watson)\..*(live|microsoft|msn|windows)
This is in DNS static entries and I am running RouterOS 6.48.2.
Wiki page doesn’t mention anything about regex complexity, length limits, number of alternatives or capturing groups allowed.
Shouldn’t this regex work?
I’d say it should work as such, but it’s too complex, to the developer’s opinion, for a DNS regexp. And I cannot imagine how to document the “acceptable complexity of a regexp” in the manual.
So try to split it into four rows, expanding the second () into one word per row; if it doesn’t help, you’ll have to expand the first () into multiple rows as well.
Content-wise, did you really intend it to match e.g. on watson.keepalive ? I mean the .* between the actual dot and the second ().
You spent more CPU for RegExp than add the static DNS…
