The National Stock Exchange (NSE) on March 11, 2026, issued circular regarding the Digital acceptance of requests for the changes related to IP and CaaS offering.
The National Stock Exchange of India (NSE) has announced revisions to its colocation (Colo) framework, modifying provisions from circular NSE/MSD/67756 dated April 29, 2025. One major change is the increase in the maximum number of permissible Interactive IPs across rack variants used by colo participants, including those used by CaaS (Colocation as a Service) vendors. The limit has been raised from 2×60 to 2×80 for High Power Density (HPD) racks, 60 to 80 for Full racks, 30 to 40 for Half racks, and 15 to 20 for Quarter racks, allowing participants greater connectivity capacity.
The exchange has also revised the CaaS framework to provide greater operational flexibility. Vendors offering CaaS can now apply for any rack variant (HPD, Full, Half, or Quarter) depending on their business requirements. Several earlier restrictions have been removed, including the limit on the number of members per rack, the rule allowing members to have only one contract with a vendor (up to two vendors), and the cap of four order connectivities per member–vendor combination.
With these changes, members can now engage with multiple CaaS vendors and request any number of order connectivities, subject to the maximum IP limits for each rack type and the exchange’s power consumption limits. The updated system for digital acceptance of rack requests, IP allotment, and TM enrolment will be available on ENIT from March 16, 2026, while all other provisions of the April 2025 circular remain unchanged.
