This makes no sense to me either. When searching bing while using 126.96.36.199 dns the results are not what expected. In particular when searching for my own website Mintyslippers.com it shows no results. Even a lookup using url:Mintyslippers.com it shows no results. However when I switch to my mobile network everything is as normal. How can your dns affect the contents of a search engine index I hear you ask. No idea I answer but this may be affecting other domains. How can bing say we don’t exist?
This happens in all browsers, signed in or out and incognito mode too.
