    Can you post a sanitized dump of the scan? Are the
    source ports incrementing by one and scanning port 53?
    This is a common trait of BigIP it gathers RTT and
    other stats so that it can properly route you to the
    least loaded server via local load-balancing. 
    The only concern I might have is the fact that IRC is
    reported as listening on port 6667. It could be a
    compromised host. BigIP uses a modified version of
    FreeBSD. I don't remember it using this port, but I
    could be wrong.
