Summary

Universiti Malaysia Sarawak

Malaysia · AI-generated

education university research

UNIMAS-MY is operated by Universiti Malaysia Sarawak.

What it's used for

  • The address space carries university infrastructure, evidenced by reverse DNS entries such as 128-subnet236.unimas.my and 255-subnet238.unimas.my.
  • The AS announces 1024 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained network typical of a single-site institution.
  • Traffic consists of academic and administrative users, including students and staff, accessing research resources and general internet services from the campus in Kota Samarahan.

Notable

  • Registrants for both prefixes are UNIMAS, matching the AS holder and confirming direct ownership of the address space.
  • The inventory is compact, consisting of two contiguous /23 blocks within the 49.50.236.0/22 range, with no IPv6 prefixes currently announced.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
