The companion port to 1047, registered to the same discontinued Sun NEO ORB.
IANA assigns 1048 to neod2, the second "Sun's NEO Object Request Broker" entry, registered to an individual with no date and no reference document. Sun's NEO distributed-object product dates from the 1990s and has been gone for many years, so the pair 1047/1048 is a historical registration rather than a live service. As with its neighbours in the 1025-5000 band, anything actually listening on 1048 is more likely a dynamically assigned RPC endpoint or an application that picked a free low port.
Expose with care
No live protocol behind the registration; identify the owning process before assuming an open 1048 is harmless.
