Summary

TasmaNet

Australia · AI-generated

isp residential business australia

FIELD-AU is the AS handle for TasmaNet, an Australian internet service provider.

What it's used for

  • The address space carries TasmaNet infrastructure and leased customer blocks, evidenced by netnames TASMANETPTYLTD-AU, VETTRAK-AU, CCAMLR-AU, BLUNDSTONE-AU, and ISW-AU.
  • With 4352 IPv4 addresses, 15 IPv6 prefixes, and 10 observed neighbours, the ratio indicates an access network serving end-users and business clients rather than a transit provider.
  • Traffic consists of residential broadband subscribers and business endpoints, including specific corporate clients like Blundstone Australia and ISW Technology, as well as the Commission for the Conservation of Antarctic Marine Living Resources.

Notable

  • Registrants for the largest prefixes align with the announcer, listing Tasmanet Administrator and TASMANET for the primary blocks.
  • The inventory includes /24 blocks registered to distinct third-party organisations such as VETtrak Pty Ltd, Blundstone Australia Pty Ltd, and ISW Technology Pty Ltd, indicating leased space or post-acquisition history.
  • The address inventory is a mix of larger /22 and /23 blocks for TasmaNet and smaller /24 blocks for specific corporate entities.

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.
