Summary
Ioffe Physical-Technical Institute
education research legacy
The network of the Ioffe Physical-Technical Institute of the Russian Academy of Sciences (IOFFE-PHYSICAL-THECHICAL-INSTITUTE-AS), a major physics research institute in Saint Petersburg.
What it's used for
- Campus and research networking for the institute: laboratories, staff, and connectivity to the wider Russian academic network.
Notable
- Institutional research address space, not commercial. Hosts here are lab and university-style systems rather than customers of a service provider.
- The low AS number and the small, long-held prefixes reflect an early academic allocation from the era when research institutes were among the first organisations on the internet in their countries.

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 1,782 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.
