Summary

Core Telecom

Romania · AI-generated

telecom business rumania

The AS handle DYNAMIC-AS is held by Core Telecom S.R.L.

What it's used for

  • The address space carries infrastructure for a Romanian telecom operator, evidenced by netnames RO-CORETEL-20190807 and RO-CORETEL and reverse DNS entries pointing to toptel.ro.
  • The AS announces 1536 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that indicates an access or business network rather than a transit provider.

Notable

  • Registrants for both announced prefixes are listed as Cerbu Nicu Alexandru; Core Telecom S.R.L., which aligns with the registry holder name.
  • The address inventory consists of two distinct IPv4 blocks: 45.138.64.0/22 and 193.239.212.0/23, with no IPv6 prefixes in the inventory.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
