Summary

Zumbak

United Kingdom · AI-generated

business uk small

The AS handle ZUMBAK is held by Zumbak Ltd.

What it's used for

  • The address space is registered under the netname IPV4C-PART-153-56-150-0 for ZUMBAK LTD.
  • The network announces a single IPv4 prefix, 153.56.150.0/24, comprising 256 addresses, with no IPv6 inventory.
  • With only one observed neighbour, the routing footprint is minimal, consistent with a small-scale internal or dedicated business connection rather than a transit or large access network.

Notable

  • The RDAP registrant ZUMBAK LTD matches the AS holder, confirming direct ownership of the announced space.
  • The inventory consists of a single /24 block, indicating a compact and self-contained address allocation.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
