Summary
internic Datenkommunikations
isp hosting business legacy
An Austrian provider announcing its own space alongside blocks belonging to other people.
What it's used for
- Business connectivity and hosting. 8,704 addresses in three IPv4 prefixes, one IPv6
/32, 35 observed BGP neighbours.
Notable
- Three prefixes, three unrelated registrants. The
/19is the provider's own, under the netnameAT-PSC-990125.87.76.163.0/24isNihaoHostingeU, registered to Verisunucu.net with an IPBNB abuse contact.192.133.109.0/24isInternic-VOIP, registrant unknown. - 35 neighbours against 8,704 addresses is a lot of interconnection for the size — this is a network that peers rather than one that just buys transit.
- The provider's own netname stem is
PSC, which matches neither the company name nor the AS handle.
Interesting
- IPBNB is an address-leasing marketplace, and the
/24under it is a Turkish hosting brand's block being announced from an Austrian AS. Leased IPv4 moves like this constantly now: the registry says who owns the numbers, the routing table says who is currently using them, and the two answers have less and less to do with each other. - The company shares its name with InterNIC, the body that ran domain registration for
.comand the rest of the early internet. Unrelated, and considerably longer-lived.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
