Summary
AR Telecom
telecom isp business
A Portuguese operator announcing a /16, with every block still named after a company it used to be.
What it's used for
- A Portuguese telecommunications provider. 75,008 addresses across four IPv4 prefixes, one IPv6 prefix, and ten observed BGP neighbours.
Notable
- The inventory is
213.63.0.0/16,213.141.0.0/19,185.113.156.0/22and194.60.91.0/24. - Two blocks carry
PT-JAZZTEL-netnames dated20000329and20150817, fifteen years apart. 194.60.91.0/24is namedNET-194-60-91-0-24, a label generated from the block itself.- The registry lookup for
213.141.0.0/19failed, so nothing here describes that block's record. - Twelve addresses were sampled and none returned a name.
Interesting
- Both dated netnames name a different company, and one of them was created in 2015, long after this operator took the space over. Whoever registered the newer block copied the naming pattern from the older ones rather than using the current name, so a defunct brand propagated forward into a record that had no reason to carry it.
NET-194-60-91-0-24is what a netname looks like when nobody chose one. The registry generates a label from the address range so the field is not empty, and the result identifies the block without saying anything about it. Every such name in the data marks a block that was created administratively rather than requested by a person.- A /16 is 65,536 of this network's 75,008 addresses, and it dates to March 2000. Portuguese operators of that era received large blocks before allocation policy tightened, and the resulting shape is one enormous prefix with a few small modern ones attached.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
