AS8585 INTERNET-CG

Crnogorski Telekom a.d. Podgorica (INTERNET-CG), Montenegro's incumbent

telecom operator and a Deutsche Telekom subsidiary. This AS carries its internet

access network.

What it's used for

• Consumer broadband: the sampled reverse DNS is dense with subscriber-pool naming under crnagora.net, such as adsl-bb0-l1.crnagora.net and adsl-lns3-l100.crnagora.net. The lns labels are the L2TP access concentrators the DSL sessions terminate on.
• Around 123,000 IPv4 addresses across 14 prefixes, plus IPv6 — a plausible size for a country of roughly 600,000 people.
• Core services also sit here (ns1.crnagora.net, and telekomcg.com hosts in 195.66.164.0/24).

Notable

• crnagora.net was the operator's original internet brand and predates the Crnogorski Telekom name; the whole subscriber estate still resolves under it.
• Ten observed neighbours, which is a lot for a small national operator and reflects its role as Montenegro's main international gateway.

Interesting

• Some addresses carry names of other regional operators (for example kujtesa.…crnagora.net and Promonte….crnagora.net), the fingerprints of interconnect and wholesale links to neighbouring Balkan networks rather than of space that belongs to them.
