About this network

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. Beograd or UGNI-RIPE.
• The address inventory is composed of a mix of larger blocks (such as 213.244.208.0/20 and 89.207.192.0/21) and smaller /22 and /24 allocations, reflecting a diversified portfolio of acquired or allocated space.
