What is IPv6?

IPv6 is the network layer protocol that has been implemented to replace the widely used IPv4. The new IPv6 is referred as the next generation internet and comes with more enhanced features than the IPv4. The main reason behind the change is that IPv4 has completely exhausted its space for new address. It uses the 32-bits that has about 4 billion IP addresses. The explosive growth in the usage was not envisaged at the time of implementation of IPv4.

IPv6 address major security issues. IPv4 was designed at a time when the internet was cleaner and so the thought of security was not given much importance. IPv6 comes with IPSec as one of the crucial requirements. IPSec is a security structure containing several cryptographic protocols like Authentication header(AH), Internet Key exchange protocol(IKE) and Encapsulating Security Protocol(ESP) ensuring network-level security. Leading web hosting providers keeping up with the IPv6 requirements provide high level protection against DDos attacks, zero-day threats SQL injections and cross-site script attacks.

IPv6 now has over 340 trillion, trillion, trillion IP addresses and carries a 132-bit code. It is designed to be more secure than the earlier version. It also offers support for mobile device (MIPv6) that enables mobile devices to switch between networks allowing roaming accessibility. Web hosting providers are ready and transiting their client’s website with the IPv6 for the website visitors to access the content in different ways and devices. To increase the mobile visitor’s experience, the hosts are deploying CDN servers optimizing delivery of content, images to mobile devices.
