About this network

The AS handle SERBIA-BROADBAND-AS is held by Yettel d.o.o., the Serbian subsidiary of the Yettel Group.

What it's used for

• The address space carries residential cable broadband traffic, evidenced by reverse DNS records such as cable-178-148-128-0.dynamic.sbb.rs and netnames like RS-SBB-NET-20100319.
• The AS announces 496,384 IPv4 addresses across 27 prefixes and maintains 170 observed neighbours, a ratio indicative of a major access network serving end-users rather than a transit provider.

Notable

• Registrants for the majority of prefixes are listed as Yettel d.o.o., aligning with the current operator, though one prefix (5.22.176.0/20) is registered to UGNI-RIPE with the netname SBBNET.
• The operator was formerly known as Serbia BroadBand (SBB) before being rebranded to Yettel following the acquisition by the Yettel Group.
• The inventory consists of a large, contiguous block of IPv4 space, including a /15 and multiple /16s, reflecting a substantial domestic footprint.
