the ipv4 vs ipv6 growth debate

Mon Dec 5 17:31:49 UTC 2022

With IPv6Foo you can click on the icon and it will show you a table listing
what URLs are serving some piece of a given page with v6 and v4.

LinkedIn for example shows the main feed page served via v6 but there are a
couple of pieces with v4 from these sites

- dpm.demdex.net
- lnkd.demdex.net
- p.adsymptotic.com
- radar.cedexis.com
- sb.scorecardresearch.com
- trkn.us

Some may be feeding ads content, others tracking, market research, etc.

Jorge
