Why are we switching from IPv4 to IPv6?
IPv6 has a redesigned header, having half the fields of IPv4. This takes up an available address, creating the need for IPv6. There are not enough addresses in IPv4 to support all of these devices. IPv6 also allows for more secure communications between these already insecure devices.
What are some of the challenges in transitioning from IPv4 to IPv6?
Difficulty in detecting and managing unknown or unauthorized IPv6 assets on existing IPv4 production networks. The added complexity of operating parallel IPv4 and IPv6 networks. A lack of IPv6 maturity in security products. The proliferation of IPv6 and IPv4 tunnels can complicate defenses.
Are there benefits to switching from IPv4 to IPv6?
Beyond the fact that IPv4 addresses have simply run out, there are numerous benefits businesses can gain by switching to IPv6, notes Mark Dargin, a network and security engineer currently with GE Healthcare’s customer technology and cloud services team, in a Network World post.
Is it possible to get IPv4 blocks?
Getting IPv4 blocks are NOT an assumption and require documentation and justification – which means that if you need routable IPv4 space – get in line with everyone else. There is good news though – IPv6 deployments have been increasing and chances are you are already using IPv6 – but haven’t realized it yet.
How does IPv6 affect a dual stack network?
Since IPv6 is most likely “not replacing” your IPv4 network, you will be running them concurrently – which impacts things financially since there are direct operational costs. You got it – dual-stack = two networks, so you are going to need to present this effectively so it doesn’t come across as “double the workload”.
What happens when a network migrates to IPv6?
“As the network evolves and migrates further towards IPv6, it will progressively lose more communication with the network until the device is replaced with one that supports IPv6.” Further, Sophos says that companies should be cautious about network tunneling during the transition period.
