Add Block programmatically: What IP encoding method

I would like to add IPs to _wfblocks7 programmatically to provide an easy for for WC Shop Managers to block fraudsters.
However, I can’t seem to get it encoded into the proper IPV6/HEX format.
SPAMMER example:
How do I convert 98.208.240.124 to 00000000000000000000ffff62d0f07c so I can save it to the database.
What method or function should I use?
