Summary
Software Technology Parks of India (STPI)
government isp legacy
AS9430 (STPI-NOIDA) is held by Software Technology Parks of India, an autonomous body under India's Ministry of Electronics and Information Technology. STPI is unusual in being a government organisation that also holds an all-India ISP licence: it has provided data-communications, internet and leased-line services to IT and software-export units since the early 1990s. The handle points at its Noida (Block-IV) facility.
What it's used for
The AS originates 34 IPv4 prefixes totalling 8,704 addresses, plus 4 IPv6 prefixes (2402:ef09::/32, 2402:ef0f::/32, 2402:ef15::/32 and a /48). Every single IPv4 announcement is a /24, and they are scattered across a wide set of unrelated ranges — 164.164.x, 203.100.x, 203.129.x, 203.190.x, 203.193.x, 161.248.26.0/24, 103.35.120.0/24. That pattern fits STPI's role precisely: it hands small blocks to the IT companies sitting in its parks and gateways around the country, and announces each one individually. The sampled reverse DNS is consistent with that — the two PTRs seen resolve under pugmarks.in, a third-party Indian provider, which is what customer-assigned space looks like rather than the operator's own infrastructure. Only 7 BGP neighbours are observed, so this is a modest gateway network buying transit, not a national carrier.
Notable
- Every IPv4 route is a /24; there is no aggregate anywhere in the announcement set.
- The rDNS that does exist points at a third party's naming, reinforcing that the space is delegated out to hosted units rather than used by STPI itself.
- STPI is a government body with a commercial ISP licence, so it sits on the government/ISP boundary rather than cleanly on either side.

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
5 upstream, 2 downstream and 10 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 2026-10-11, 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: 432 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.
