icao 24 hex coding

[hispeedbypass]

Could anyone point me to where I can get a listing of aircraft hex codes to add to Basestation.  Eg. new airliners over recent months as well as biz jets.
While G-INFO or N Numb are useful on a one reg search I'm looking for a current listing of all available Hex codes instead of having to rely on Basestation to ping aircraft, then trawl through later to update details such as types/ ops flags etc.
I know some years ago lists seemed to be found on websites. I cannot seem to find them now.
Often sites that list airlines including Registrations (such as planespotters.net)list all the other info including aircraft names, seating spec etc. but not 6 alphanumeric code needed for Mode S inclusion, so anyone who could point me in right direction would be most appreciated.
Thanks Julian
