You could try this:

Code:
STR2=159
END2=200
for ((i=STR2; i<=END2; i++))
do
    printf -v HEX "%016x" $i
    printf "%s:%s:%s:%s\n" ${HEX:0:4} ${HEX:4:4} ${HEX:8:4} ${HEX:12:4}
done

But be aware you will run into an issue with IPs greater than "7fff:ffff:ffff:ffff" as bash uses signed 64-bit integers. The highest order bit is a sign bit and so the integer representation of these values will be a negative number:
Code:
  -1 = ffff:ffff:ffff:ffff
  -2 = ffff:ffff:ffff:fffe
...
-256 = ffff:ffff:ffff:ff00
...
-9223372036854775807 = 8000:0000:000:0001
-9223372036854775808 = 8000:0000:000:0000
 9223372036854775807 = 7fff:ffff:ffff:ffff
 9223372036854775806 = 7fff:ffff:ffff:fffe
