Summary
UGNI
transit isp serbia nsp
The AS handle UGNI is operated by UGNI United Group Network Infrastructure d.o.o. Beograd.
What it's used for
- The address space carries infrastructure for a Serbian network service provider, with registrant netnames consistently formatted as
RS-UGNI-YYYYMMDD(e.g.,RS-UGNI-20030611,RS-UGNI-20091207). - The AS announces 12,544 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, while maintaining 880 observed neighbours. This high neighbour count relative to the address inventory indicates a transit or network service provider role rather than a pure access network.
Notable
- All registrants in the RDAP data align with the announcer, identified as
UNITED GROUP NETWORK INFRASTRUCTURE d.o.o. BeogradorUGNI-RIPE. - The address inventory is composed of a mix of larger blocks (such as
213.244.208.0/20and89.207.192.0/21) and smaller /22 and /24 allocations, reflecting a diversified portfolio of acquired or allocated space.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
