Summary

SUNY Health Science Center at Syracuse

United States of America · AI-generated

education university research medical

The AS handle SHSC-1-AS is held by State University of New York, Health Science Center at Syracuse.

What it's used for

  • The address space carries the institutional network for a SUNY medical center, identified by the netname SUNYHSCSYR and registrant name.
  • The AS announces 65536 IPv4 addresses within a single /16 prefix (139.127.0.0/16) and maintains 4 observed routing neighbours, a ratio consistent with an internal educational or research network rather than a transit provider.

Notable

  • The RDAP registrant matches the AS holder exactly, confirming the space is directly owned and operated by the university.
  • The address inventory consists of a single contiguous /16 block, typical for a large institutional campus requiring a substantial amount of address space for internal segmentation.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-21. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
