Summary

Nicom Wireless

Hungary · AI-generated

mobile residential hungary

NICOM-AS is operated by Nicom Wireless Kft.

What it's used for

  • The address space carries fixed IP endpoints, as indicated by reverse DNS records such as fixip160.128.nicom.hu and fixip163.64.nicom.hu.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with an access network providing connectivity to end-users.
  • Traffic from this AS consists of subscriber traffic for mobile and fixed-line internet access services in Hungary.

Notable

  • Registrant data for both announced prefixes lists 23VNet Kft.; The 23Net Network Management under the netname HU-NET23-20111219, which differs from the AS holder Nicom Wireless Kft.
  • The inventory is small and concentrated in the 37.17.160.0/23 and 37.17.163.0/24 ranges, with no IPv6 prefixes announced.

Reputation

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 1,779 prefixes, as published 2026-10-24. 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.
