The age of IPv6 is Upon Us ARIN, the American Registry for Internet Numbers is the authority in charge of distributing IP addresses in North America. ARIN received the IPv4 blocks for North America from the IANA (Internet Assigned Numbers Authority, which is responsible for distribution of IP addresses and maintaining DNS root zones as…
Take a look at the difference between how a page (msnbc.com) loads from an IPv6-Only monitoring location and a monitoring location with native IPv6 or 6to4 translation. You may want to think about running an IPv6 test on your own websites after seeing these results.
Dotcom-Monitor now offers a dedicated IPv6 monitoring location, which means that tasks being monitored from this location will not be able to resolve traffic across an IPv4 network, so if the communication cannot travel across an IPv6 compatible network, this location will return a failed monitoring result.
Now you can test IPv6 connections specifically from an “IPv6 only” location to ensure that your services are accessible via IPv6 only nodes. This is useful for testing IPv6 specific resolution because there are configurations available on different networking devices that may allow traffic between IPv4 and IPv6 nodes that will not work with IPv6-Only nodes. For example, it is possible that you may have a router on one end of the communication that attempts to send IPv6-Only traffic using a tunneling mechanism to tunnel IPv6 through an IPv4 only network while the router on the other end is not capable of extracting the IPv6 address from the IPv4 tunneled data.
Utilizing an IPv6 location also allows you to ensure that any APIs you use are capable of handling IPv6 communications. The IPv6 monitoring location will let you know if your application is not IPv6-aware by triggering an alert when the application is unable to respond.
External IPv6 Monitoring for IPv6-Enabled Services
As highlighted by the upcoming IPv6 Day on June 8, the need for a new Internet Protocol (IP) is well understood and accepted in the networking industry.
Requirements for more address space, simpler address design and handling at the IP layer, better Quality of Service (QoS) support, greater security, and an increasing number of media types and Internet-capable devices have all contributed to drive the development of Internet Protocol version 6 (IPv6).
What is less well understood certainly are aspects of how external monitoring helps identify key challenges for businesses using IPv6, specific areas for IPv6 performance monitoring, and the benefits of external IPv6 performance monitoring. Firstly, for brevity sake are some of the basic aspects of IPv6-related monitoring are noted in the grid below and the services to test and monitor. Then, a longer, detailed notes on the aspects of IPv6 as related to external monitoring.
