Australia · AI-generated

msp business fibre nbn

The AS handle ANTICLOCKWISE-AS-AP is held by Anticlockwise Pty Ltd.

What it's used for

  • The address space carries business internet and managed services, evidenced by netnames ANTICLOCKWISE-AU and ANTICLOCKWISE-AP and reverse DNS entries like gus.barnet.com.au and www.mavetju.org.
  • The network announces 11,776 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a role focused on delivering access to business clients rather than providing transit.
  • Traffic from this AS consists of business fibre internet, NBN connections, managed WiFi, and workplace technology solutions for corporate clients in Australia and internationally.

Notable

  • Registrants for the majority of prefixes are Anticlockwise Pty Ltd, while the prefix 103.67.20.0/24 is registered to E & P IT Solutions Pty Ltd under the netname EISPL-AU.
  • The address inventory is finely subdivided into multiple /23 and /24 blocks, consistent with an internal corporate estate or segmented business access network.

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: 431 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.
