    Seamus,
      Careful with VR (and NeoTrace) -- they're susceptible to GIGO
    (garbage in...). They're based on the POC input of the various
    ISP/NSP routers (from ARIN, etc., dB) along the way and while the geo
    stuff looks cool, it may not be where the box really is sitting in a
    rack...conversely, just because an "owner" is in San Mateo doesn't
    preclude the web-host, for example, from being in Paramus...
      The "one stop shop" I really like is http://combat.uxn.com which is
    basically a front-end linking several registration bureaus & search
    options on one page. Includes ARIN, European RIPE, GEEKTOOLS whois
    front end, & some other tools all on a single webpage. Very handy.
    BTW, it's sometimes useful to check more than one registry...I
    recently detected either a 1. "in process" change-over of ISP/NSP
    number assignments or 2. a DNS zone-transfer hack in progress. (See
    SANS http://www.sans.org/y2k/010201.htm )
