Enabling Technologies

New technologies are essential to enable the Internet to keep growing, evolving and meeting the changing expectations of users. Enabling technologies contribute to improved Internet scalability, security, trust and availability.

Internet Society Pulse curates information about levels of IPv6 adoption in countries and networks around the world, progress being made towards an encrypted web, indicators of DNSSEC adoption by the registries for country-code domain names, and data on worldwide adoption of TLS1.3 and HTTP/3.

Global Growth of Enabling Technologies

The charts below show the global growth of key enabling technologies – TLS1.3, HTTP/3, IPv6 and DNSSEC – over time using the latest information from our data partners.

TLS 1.3

Many popular Internet applications like e-mail and web browsers use Transport Layer Security (TLS) to secure traffic against eavesdropping and against data being tampered with while in transit between clients and servers. Over time, flaws in early versions of TLS have been identified leading to substantial improvements to the protocol.

The latest version, TLS 1.3, provides enhanced security and fewer ways for attackers to find new flaws. TLS 1.3 has also been shown to improve performance, with secure connections taking less time to be established. This helps to demonstrate that optimizations can be made without compromising on security. Improving the security of Internet applications of all kinds is imperative for a healthy and growing Internet.

Hypertext Transfer Protocol (HTTP) is a fundamental part of the World Wide Web. In addition to powering the web, HTTP is increasingly used to transfer data between Internet-connected devices of all kinds. The latest version of HTTP (HTTP/3) marks quite a radical departure from the past by adopting a completely new transport protocol (QUIC).

The ability for the Internet to embrace HTTP/3 indicates the Internet’s capacity to keep evolving and supporting new applications. As the Internet has matured, deploying new protocols to improve performance and/or security can be difficult. The introduction of a new transport protocol for something as popular and important as HTTP is a real test of the capacity of today’s Internet to continue to support growth and innovation.

IPv6 is the latest version of the fundamental technology (Internet Protocol) that powers the Internet. The previous version, IPv4, is still in operation on many networks around the world but it can only support an Internet of a few billion devices. By contrast, IPv6 can support an Internet of billions of billions of devices and can provide enough address space to meet the needs of the growing Internet for decades to come. Simply put, the Internet has outgrown its original design and IPv6 is the solution.

Internet Society Pulse presents measurements of IPv6 adoption to raise awareness of the different levels of IPv6 adoption in different countries and networks around the globe, and to encourage greater adoption of this important enabling technology.

Just about every Internet communication starts with a Domain Name System (DNS) lookup. The DNS is an essential piece of Internet infrastructure that translates human-friendly names (internetsociety.org) into computer-friendly numbers (2001:41c8:20::b31a).

Like many other components of the Internet, the DNS started out in an insecure form in a vastly different Internet landscape. Today, security and trustworthiness are vital foundations for the ongoing evolution and growth of a robust Internet that benefits users everywhere. DNS Security Extensions (DNSSEC) was developed to provide an additional level of security using cryptographic techniques to validate the authenticity of DNS information.

Internet Society Pulse presents indicators of DNSSEC adoption by the registries for country-code domain names (ccTLDs) and a measurement of the use of DNSSEC validation by Internet hosts globally.
