  IIJ Develops SMF-LAN, Network Management System for Closed Networks
  -- Providing centralized administration of communications equipment to carriers using IPv6 --


TOKYO, March 23, 2005 -- Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI), one of Japan's leading
Internet access and comprehensive network solutions providers, today announced the release of
SMF-LAN (*1), a new network service platform that enables centralized control of initialization,
reconfiguration, and other operations involving communications equipment on closed networks such as
wide-area Ethernet services.
(*1)
       Patent Pending (Application 2004-322198)

Since June 2003, IIJ has been operating the SMF network management system, which provides
centralized remote administration of routers over the Internet. Customers rave about this system’s
ability to cut operation and administration costs, its high security, and its user-friendly interface. It is
currently used in over 3,000 locations by communications carriers providing Internet-based VPN
services and companies building multi-node, nation-wide networks using VPNs.

SMF-LAN gets its foundation from SMF technology and uses that technology to create a network
management system that can provide the same functionality on wide-area Ethernet services and other
closed networks. Communications carriers providing wide-area Ethernet services can use SMF-LAN as
their service platform and greatly reduce the cost of maintaining routers on customer premises and
reduce the network administration costs for end users building a WAN using wide-area Ethernet.
Communications between the devices on the SMF-LAN system use IPv6, which enables centralized
management of communications equipment without impacting the customer’s existing IPv4 network.

KVH Co., Ltd. will incorporate the SMF-LAN system into their managed Ethernet service,
“Ether-MAN” in order to simplify the service installation process.

IIJ will continue to provide SMF to communications carriers and companies with nation-wide locations,
and hopes to reach 12,000 locations during the 2005 fiscal year.


SMF-LAN Features
- Automated configuration
     When connected to the LAN, IIJ’s proprietary SEIL Series router automatically reads the configuration
     file and completes its own configuration. No need for users to directly configure the router.
- Configuration and feature update (push technology)
     Settings and features can be distributed from the LAN-administration server to specific equipment
     (such as routers) at administrator-defined times.
- Proxy monitor and notification feature
     This feature acts as a proxy for the monitoring system and notifies a specified monitoring server of its
     results.
