You might try something like
var %entry2 = $hfind(iptracker,$+(*,$chr(32),%entry,$chr(32),*),%c,w).data
This presumes that each proper ip address is space separated in the data.
eg: 1.2.3.4 1.2.3.40 1.25.36.495
I tried something like your example, but w/o the wildcards on the end. Your example didn't work either. Hum.
