About this network

ICICIBANK-AS is operated by ICICI Bank Limited, a major Indian commercial bank headquartered in Mumbai.

What it's used for

• The address space carries internal corporate infrastructure, evidenced by netnames such as ICICIBANK-IN, ICICIBANK-AS-AP, and ICICIBank registered to ICICI Bank Limited.
• The AS announces 5632 IPv4 addresses across 12 prefixes and 2 IPv6 prefixes, while maintaining only 4 observed neighbours, indicating a self-contained internal network rather than a transit or access provider.

Notable

• Registrants for the majority of prefixes align with the announcer, specifically ICICI Bank Limited, though some blocks like MCDAAVSPL, EVASOFT, TRAXINDIA, WOLBES, and LRS are registered to third parties, suggesting leased or historically allocated space.
• The inventory consists of finely subdivided /23 and /24 blocks, consistent with site-by-site segmentation for a large corporate estate.
