AS9730 — BHARTITELESONIC-AS-IN-AP - Bharti Telesonic Ltd

AS9730 announces 6 IPv4 prefixes covering 1,536 addresses and 1 IPv6 prefixes.

About this network

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.
