So, as someone else mentioned, it appears to show historical records, I'm not sure what the TTL on these is, but some of the open ports on my dynamic IP are from previous "owners" of the IP, aren't actually open any more. For the HTTP/S ports, it displays the response headers, including timestamp, so I went through my access logs and found the record, if anyone is curious: 71.6.165.200 - - [xx/Sep/2020:xx:xx:xx +0000] "GET / HTTP/1.1" 200 612 "-" "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36" 71.6.165.200 - - [xx/Sep/2020:xx:xx:xx +0000] "GET /robots.txt HTTP/1.1" 404 163 "-" "-" 71.6.165.200 - - [xx/Sep/2020:xx:xx:xx +0000] "GET /sitemap.xml HTTP/1.1" 404 163 "-" "-" 71.6.165.200 - - [xx/Sep/2020:xx:xx:xx +0000] "GET /.well-known/security.txt HTTP/1.1" 404 163 "-" "-" 71.6.165.200 - - [xx/Sep/2020:xx:xx:xx +0000] "GET /favicon.ico HTTP/1.1" 404 135 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:80.0) Gecko/20100101 Firefox/80.0"
