Seven Internet Exchange Nodes are functional at Delhi (Noida), Mumbai, Chennai, Kolkata, Bengaluru, Hyderabad and Ahmedabad. The Internet Exchange nodes have been successful in ensuring peering of Internet Service Providers among themselves for the purpose of routing the domestic traffic within the country, instead of taking abroad, thereby resulting in better quality of service (reduced latency) and reduced bandwidth charges for ISPs by saving on International Bandwidth. 

NIXI also manages the .IN Registry (www.registry.in). At present, 104 Registrars have been accredited to offer .IN domain name registration worldwide to customers. This has helped in proliferation of web hosting in the country and enhancement of Indian language content on the Internet. Over 17 lakhs .IN domain names have been registered till March 2015. 

NIXI is also entrusted with the responsibility for setting up the National Internet Registry (NIR) for India. NIR has been named as Indian Registry for Names and Numbers (IRINN). IRINN is responsible for allocation of IP address and AS Numbers within the country.
