i feel left out - i am still stuck with a human-readable IPv4 address...
do you have IPv6 connectivity?

IPv4 Address:
125.12.3.65
IPv6 Address:
2145:00D5:2F3B:0000:0000:00FF:EF00:98F3

it seems i have an additional IPv6 address.. in case!
I would postpone this for now. I think Ipv6 won't still be used for another 5 years. NAT is still very effective.
