    Actually that's there because Scott Perry (the owner of that page) and I
    have a disagreement. SORBS has a listing and delisting policy that is
    published, Scott Perry can't/won't fit himself into the delisting rules
    (he has/had generic DNS with short TTLs in the middle of a verified
    dynamic pool and no SWIP indicating that it was assigned to him), and
    for that reason I refused to delist him - I told him that he should set
    non generic rDNS, or rDNS indicating static assignment with TTLs of at
    least 43200 seconds or get SWIP'd - that note has been on his page since
    the day I refused to delist him.

    Depends - the SORBS DUHL has strict list and strict delist policies and
    (outside of errors - human ones) doesn't have many issues with statics
    being listed as dynamics. It is a full time job for 3 staff keeping up
    with network renumberings and reallocations and from time to time we get
    behind, however we always catch up.
