Une LiveBox Jet fibre vient d'être installée à mon domicile.
Les sites suivants sont soit inaccessibles, soit ont un délai d'accès extrêment long, alors qu'ils étaient accessibles quotidiennement immédiatement sur ma box Bouygues Télécom en IPv4:
- httpredir.debian.org (la redirection est variable)
- http.debian.net

Vous remarquerez que certaines adresses IPv6 sont accessibles et d'autres non.
Il est impossible de mesurer le RTT à l'aide de "ping6", car il semble que les pings soient bloqués à partir d'un certian routeur :
