About this network

The AS handle DELDLCORE-AS-AP is held by delDSL Internet Pvt. Ltd.

What it's used for

• The address space carries residential and business access traffic, evidenced by netnames such as DELDSL-IN and DELTEL, and reverse DNS entries like ptr-203-110-93-254.deldsl.net.
• The AS announces 6,912 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants are largely consistent with the announcer, with most prefixes registered to IRT-DELDSL-IN, though 103.242.224.0/22 is registered to IRT-IRINN-IN and 103.142.18.0/24 to IRT-THSIN-IN.
• The address inventory is subdivided into multiple smaller blocks, including several /24s and /23s, alongside larger /21 and /22 allocations, reflecting a segmented internal estate for different service tiers or regions.
