"Your cellphone primarily uses IPv6. Its IPv4 connectivity is a kludge of carrier-grade NAT and a collection of workarounds that I’d call black magic if the Evil Wizards Union wouldn’t sue me for slander."
Networking for Systems Administrators, 2nd edition, is now open for sponsorships. 23 more print sponsors and I'll do another challenge coin.
@mwl not a single polish GSM carrier does IPv6 by default. At least two of them do only for business contracts. The situation with residential ISPs isn’t much better, with one (UPC/Play) offering a selection between IPv6 + tunneling IPv4 to one IP half a country away or just native IPv4, and several others offering IPv6 (but turning it on breaks IPTV/telephony on their default config).
I hecking wish my phone did IPv6 - outside my wireguard tunnel, at least.
@mwl I WISH my cellphone would use IPv6!
@mwl Yeah can confirm .. my phone always seems to have functional ipv6 on cellular but apps want to do 4 and it often just doesn't work
