DGUon both announced prefixes. - The AS announces 1024 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained educational network rather than a transit or large-scale access provider.
- Traffic from this AS consists of academic and administrative users, faculty, and students accessing the internet from the university's campus in the Republic of Dagestan.
Notable

Abuse-C Rolewith the netnameDGU, which aligns with the university's abbreviation. - The address inventory is compact, consisting of two contiguous /23 blocks (194.190.250.0/23 and 194.190.252.0/23) totaling 1024 addresses.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-17. 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.
