Specified Transfer Listing Service (STLS)
The Specified Transfer Listing Service was retired on 1 June 2023. If you or your organization requires assistance with transferring IPv4 address space or Autonomous System Numbers (ASNs), the ARIN Qualified Facilitator Program can help.
The Specified Transfer Listing Service (STLS) was an optional service supported by ARIN from August 2010 until February 2023 that helped connect organizations seeking to acquire IPv4 address space, organizations looking to transfer unused IPv4 address space, and parties interested in facilitating the transfer process. The STLS was retired on 1 June 2023. The STLS was specifically for Transfers between Specified Recipients within the ARIN Region (Number Resource Policy Manual (NRPM) 8.3) and Inter-RIR Transfers (NRPM 8.4).
