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. Regards Jorge On Mon, Dec 5, 2022 at 11:09 AM Tom Beecher <beec...@beecher.cc> wrote: > Often lost in the 'debate' about V6 adoption is that for a 100% native > IPv6 experience to work, there are multiple other components that have > nothing to do with the network that ALSO have to work correctly.
