Unclassified APNIC
Summary
Software Technology Parks of India
government isp legacy
SOFTNET-AS-AP is Software Technology Parks of India (STPI), an autonomous society under India's Ministry of Electronics and Information Technology. STPI was set up in 1991 to promote software exports, and it runs its own network, SOFTNET, as the ISP for the companies inside its parks.
What it's used for
- Internet and datacom service to the IT and ITES firms that occupy STPI centres. The AS is registered to the Bangalore centre but its ~240 prefixes carry space assigned to STPI locations across the country:
164.164.0.0/16isSTPI-Bangalore,196.12.32.0/19isSTPI-Hyderabad,203.129.224.0/19is STPI Pune, and so on. - Roughly 79,000 IPv4 addresses plus a substantial IPv6 inventory under
2402:ef02::/32and2402:ef2f::/32.
Notable
- This is business address space, not consumer space. The holder is a government body, but the addresses in front of it are the software-export companies that rent space in the parks, so an address here is far more likely to be a corporate office or a company server than a home user.
- There is little reverse DNS across the inventory, which is normal for a wholesale provider that hands blocks to tenant organisations and lets them run their own naming.
Interesting
196.12.32.0/19sits inside a/8that is otherwise AFRINIC's, but it is a genuine legacy Indian assignment maintained by IRINN. Anything that infers a country from the/8alone will place STPI Hyderabad in Africa.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
6 upstream, 5 downstream and 19 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,775 prefixes, as published 2026-10-11. 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.
