Summary

Proximus

Belgium · AI-generated

telecom residential business

BELGACOM-AS is operated by Proximus NV, the primary telecommunications provider in Belgium.

What it's used for

  • The address space carries corporate and security infrastructure, evidenced by netnames BELGACOM-NET and TELINDUS-NET and registrants including Proximus Internet Anti-Fraude Center.
  • The AS announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that indicates an internal corporate estate or access network rather than a transit provider.

Notable

  • Registrants align with the announcer, listing Proximus NV and Proximus Internet Anti-Fraude Center for the announced blocks.
  • Belgacom NV/SA was rebranded to Proximus NV/SA in 2015, explaining the historical handle BELGACOM-AS versus the current corporate name.
  • The inventory consists of two distinct IPv4 prefixes, 193.243.136.0/23 and 91.190.208.0/24, 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.
