Unclassified ARIN
Summary
Operations & Technology Group
hosting enterprise legacy
AS9479 (OTG-AU) is held by Operations & Technology Group Pty Limited, an Australian company based in Neutral Bay, on Sydney's lower north shore. Its public supplier listings describe a managed IT services business — helpdesk, monitoring, licence and hardware management, plus project work across Azure, data centre, Microsoft 365, networking, security and backup. It trades in association with the Vigilant.IT brand.
What it's used for
The routing footprint is small and fits an MSP rather than a service provider. The AS originates 4 IPv4 prefixes carrying 1,024 addresses and no IPv6. The four blocks — 103.215.12.0/24, 103.246.51.0/24, 103.246.128.0/24, 103.250.63.0/24 — are all /24s drawn from different parts of APNIC's 103/8 range, i.e. four separate small allocations acquired over time rather than one aggregate that has been carved up.
One observed BGP neighbour, an Australian provider (FireNet). A single upstream rules out both a transit role and any resilience motive; the AS exists so the company can hold provider-independent address space it can renumber managed infrastructure into without depending on a carrier's assignment. That is a common pattern for managed-service and data-centre outfits of this size: the addresses number servers and customer-facing managed systems, not an eyeball base.
Notable
- Scattered /24s with no aggregate can superficially resemble an address-leasing operation, but here the blocks are all from one registry and the holder is a straightforwardly identifiable Australian operating company, which is a different thing.
- Do not confuse this with Operational Technology Solutions, an unrelated Melbourne utilities-engineering firm with a similar name.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
