Microsoft has acknowledged it runs out of Internet Protocol version 4 (IPv4) addresses in the United States sometimes, but has ensured Azure US customers that their information will stay in the United States.

Some US customers of the Azure cloud platform service of Microsoft were concerned when they discovered that some virtual machines had been assigned non-US IP addresses.

“This needs Microsoft to use the IPv4 address space accessible to us internationally,” he said.

This implies that although a service may seem as though it’s coming from a non-US location, the servers stay in the US.

“So when you deploy to a US area, your service continues to be hosted in US and your customer information will stay in the United States,” said Srinivasan.

Big firms like Microsoft bought up big blocks of IPv4 addresses, but as the amount of net-connected devices and services raise, all the IPv4 addresses that are available will be exhausted.

Because of this, businesses all over the world must begin moving over to the next-generation IP addressing system, IPv6.

In its Azure site, Microsoft says it’s constructed IPv6 support into a lot of its own goods and alternatives like Windows Server 2012 R2 and Windows 8.

The foundational work to enable IPv6 in the Azure surroundings, it asserts, is underway.

“Nevertheless, we’re not able to share a date when IPv6 support will soon be normally accessible at this time,” the firm said.

Organisations will need to alter how that they do networking as the world goes from IPv4 to IPv6 while IPv6 solves the dilemma of running out of addresses.

Most operating systems contain some type of IPv6 support by default.

This means networks have partial deployment of IPv6, frequently without IT realising. This in turn means IPv6 support may be utilized by attackers for several malicious purposes including activating VPN leakages or evading network security managements.

Second, IPv4 and IPv6 will coexist for some time, so it’s going to end up common for supposedly “IPv4-only” nodes to speak with IPv6 nodes throughout the support of transition or coexistence technologies.

This means assaults using IPv4 and IPv6 can be readily obfuscated by attackers.

Eventually, immediately, and many organisations will have to deploy IPv6 sooner or later learn the details of IPv6 security so that an educated deployment and transition strategy may be executed.
