What is the address: ::ffff:205.209.168.20
Is it the new ipv6 made to work on ipv4 or just something that I haven't seen before.
This individual (?) has made repeated attempts to ssh2 into my machine and I do not understand the address.
That is an IPv6 address. v6 addresses are composed of 128 bits, usually expressed in hexidecimal. The "::" at the beginning means a contiguous string of "0" bits, then there's 16 bits of "1"s and what appears to be a standard IPv4 address. I'm not sure, but that might be an IPv4 "compatible" address, but I'd have to look up the IPv6 specs, to be sure.
