Summary

Universitas Airlangga

Indonesia · AI-generated

education university indonesia

The AS handle UNAIR-AS-ID is held by Universitas Airlangga.

What it's used for

  • The space carries university network traffic, identified by the netname UNAIR and the registrant IRT-IDNIC-ID.
  • The network announces 4096 IPv4 addresses across 1 prefix (210.57.208.0/20) with 4 observed neighbours, a ratio consistent with an internal institutional estate rather than a transit or large-scale access provider.
  • Traffic from this AS consists of academic and research endpoints, administrative systems, and student/staff access within the university's infrastructure in Surabaya.

Notable

  • The registrant IRT-IDNIC-ID aligns with the announcer, confirming the address space is allocated to the university via the Indonesian Internet Registry.
  • Universitas Airlangga is a public research university in Surabaya, East Java, established in 1954 and designated a Legal Entity State University in 2006.
  • The address inventory is a single contiguous /20 block, typical of a dedicated institutional allocation.

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 1,781 prefixes, as published 2026-10-16. 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.
