Unclassified APNIC Enterprise
Summary
Bharti Airtel (Bharti Telesonic)
legacy isp transit enterprise
AS9730 (BHARTITELESONIC-AS-IN-AP) is registered to Bharti Telesonic Ltd, the national long-distance company of India's Bharti group, which was amalgamated into what is now Bharti Airtel Limited. The registry handle is a historical artefact; operationally this AS is part of the Airtel network.
What it's used for
The evidence is unambiguous about who runs the space: every sampled address resolves under airtel.in, in Airtel's aes-static-* naming (for example aes-static-005.97.144.59.airtel.in), which is the pattern Airtel uses for statically-assigned enterprise/leased-line customers. The routing shape is the interesting part. RIS sees only 10 IPv4 prefixes totalling 2,816 addresses and two IPv6 /48s, yet 187 observed BGP neighbours. A tiny address count against a very large neighbour count is not an access network — it is an AS used at interconnection points. This is a carrier-side AS whose job is peering and carrying a handful of specific enterprise and infrastructure prefixes, not one that aggregates a subscriber base. The bulk of Airtel's eyeball and backbone routing lives in other Airtel ASNs.
Notable
- Bharti Telesonic held the DoT national long-distance licence and launched NLD service under the IndiaOne brand before the group's carrier entities were merged; the ASN outlived the company name.
- Do not read this as "Airtel's network". It is one of several Airtel-operated ASNs, and it is the small, peering-heavy one — describe it as such rather than as India's mass-market Airtel.
- The announced set is a scatter of /24s across several unrelated-looking address ranges, consistent with per-customer and per-service routes rather than a contiguous consumer pool.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
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.
