IPv6 address is converted to its binary form {...}; The binary value is encoded to base32 (RFC 4648) {...}; Padding symbols "======" are removed from the end of the string.

You can now put text into the address like with .onion sites, or session messenger nicks.

I’ll be everywhere...wherever you look. Wherever there's a fight so hungry people can eat, I’ll be there. Wherever there's a cop beatin’ up a guy, I’ll be there. I’ll be in the way guys yell when they’re mad...I’ll be in the way kids laugh when they’re hungry and they know supper’s ready. And when our folks eat the stuff they raise and live in the houses they build...I’ll be there.
