Summary
Telekom Srbija (mts)
isp eyeball legacy
TELEKOM-AS is Telekom Srbija a.d., Serbia's state-controlled incumbent telecom operator, which sells fixed and mobile service under the mts brand. This is its main network AS.
What it's used for
- Consumer broadband across Serbia. Reverse DNS is explicit:
IP-ADDR.dynamic.isp.telekom.rson the large blocks, which is a straightforward dynamic subscriber pool naming scheme. - Space inherited from acquired cable operators, still resolving under their own domains. Prefixes in the AS carry
cpe.vektor.netandcpe.sn.co.rsdynamic CPE names, the fossils of regional ISPs Telekom Srbija bought up during Serbia's cable consolidation. - Around 820,000 IPv4 addresses across roughly 90 prefixes, with a legacy
212.200.0.0/16at the core of it.
Notable
- An eyeball network, and one of the largest in the region. The addresses front Serbian households, so they geolocate to end users rather than to servers or datacentres.
- The mix of reverse-DNS domains inside one AS is the tell that this network grew by acquisition rather than only organically. Whole customer bases were moved under the incumbent's routing while keeping their old naming.
Interesting
- Telekom Srbija's buying spree in the Serbian cable and ISP market was politically contentious at home, and the routing table quietly records it: the acquired operators' names survive in reverse DNS long after their brands stopped appearing on bills.

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: 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.
