Hello, I would like to recall this short conversation that appeared in ipv6-wg: https://www.ripe.net/ripe/mail/archives/ipv6-wg/2015-November/002747.html I was wondering if it is worth adding a new system tag to probes: something like system-dns64.

From a quick analysis that I made using RFC7050 [1] I noticed that only a handful of probes are behind a DNS64 box, but I think it would be useful to have them tagged, to avoid spending credits to detect them every time.

Or perhaps the game is not worth the candle... In that case, you can find my results as of yesterday there on GitHub. Bests, 1] https://gist.github.com/pierky/e5ec5c8f8f926bff3ef3#file-ripe-atlas-rfc7050-... -- Pier Carlo Chiodi
