alt Hacker NewsThey could buy a dedicated IPv4 address, but that address still has to be tunneled through [EDIT:] IPv6 networks if that dev has no access to [EDIT:] IPv4 networks. Thus DX still suffers. [ADDENDUM: I mistakenly swapped "IPv4" and "IPv6" there. See comments.]
I'm not sure I understand your point; if exe.dev operates a dedicated IP solely so a specific mythical IPv6-less developer can connect to a specific server, then there's no tunnelling involved at all.
