You are invited! *Live* webinar: Optimizing IP Assets: Geolocation Strategies and IPv4 Leasing Best Practices 📅 Tuesday, September 29 🕒 3pm SGT / 2pm ICT (Bangkok) / 4pm JST (Tokyo) / 5pm AEST (Sydney) ⏰ 9am CEST / 8am BST (UK) Accurate IP geolocation plays a critical role in delivering seamless digital experiences, enabling efficient content distribution, and supporting location-based services. Yet, outdated or inconsistent geolocation data can lead to operational challenges, particularly for organizations managing or leasing IPv4 address space. Our colleague Massimo Candela @webrobotics will explore how industry standards, including RFC 9092 and RFC 9632, are transforming IP geolocation by enabling network operators to publish and maintain authoritative geolocation information directly—reducing reliance on third-party updates and improving geolocation accuracy. Complementing this session, our colleague Sreekanth Vasudev will share #IPv4leasing best practices and the key considerations organizations should evaluate when sourcing IPv4 address space. He will also explain how our Global IP Network helps organizations maximize the value of their IP assets with clean, reliable, and accurately geolocated IPv4 address space. In this webinar, you will learn about: ▪ How to leverage industry standards to improve the accuracy and operational management of your IP geolocation data ▪ How @nttdata_inc and our Global IP Network ensure leased IPv4 address space is clean, reliable, and correctly geolocated to meet your business and customer requirements ▪ IPv4 leasing best practices and key considerations when sourcing IPv4 address space ▪ How our #globalipnetwork #AS2914 helps organizations maximize the value of their IP assets Register now at lnkd.in/dPxmzWTC and secure your spot. See you on September 29! #NTTDATA #livewebinar @NTTDATA_APAC @docomo
