I have a static IPv4 address from CenturyLink (x.y.z.198). To find my corresponding IPv6 6rd address I need to convert my IPv4 address to hex and append CenturyLink’s 6rd prefix.
My ipv4 address: x.y.z.198
My IPv6 6rd address: XX:YY:ZZ:C6
where XX (in hex)=x (in decimal)
Prepending CenturyLink’s IPv6 6rd prefix (2602::/24) to my 6rd address leaves me with 2602:00XX:YYZZ:C600::
