User agent

Requests from Oh Dear carry user agents like these:

Oh Dear Sitemap check https://ohdear.app

Mozilla/5.0 (compatible; OhDear/1.1; +https://ohdear.app/checker; brokenLinks)

Mozilla/5.0 (compatible; OhDear/1.1; +https://ohdear.app/checker; mixedContent)

Device Detector identifies it with this pattern (a case-insensitive regular expression):

ohdear\.app

Anyone can put any name in a user agent. Where the operator publishes IP ranges, checking the request's address against them is the way to confirm a visit is genuine.

How Vireo counts Oh Dear

Vireo keeps requests from Oh Dear out of your pageviews and visitors and counts them on its bot report under Uptime monitors, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over Oh Dear's user agents.
