Well, if you're willing to put the effort to make a sequential number system, be my guest.

Hide last two octets:

PHP Code:

long2ip(ip2long($post['ipaddress']) & 0xFFFF0000)

---

Hash:

PHP Code:

substr(sha1($post['ipaddress'] . substr($mybb->settings['internal']['encryption_key'], 0, 8)), 0, 8)

---

Quite simple really.
