residential cable broadband serbia

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.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
