IPv4 has done a great job for the internet, but their addresses are limited to 4 billion addresses. The boom of the network equipment has brought this protocol has reached its limit and ending IP addresses are.
So what happens when IPv4 runs out of space? Essentially it means that networks will lose the ability to grow (there are workarounds, but they are challenging and really only a short term bandage to the problem). IPv6 is designed to replace IPv4.
IPv6 addresses are 128 bits long (es. 22a02:29e0:4585:1:210:f8ff:fe41:65bf), compared to the 32 bit IPv4 addresses (es. 22.214.171.124). The end result is that IPv6 delivers a much larger address capacity than IPv4.
Over a multi-year transition period, both IPv4 and IPv6 will be supported. IPv6 will eventually replace IPv4.
SeFlow and IPv6
SeFlow guarantee native IPv6 support inside our network. oes not have to worry about tunneling to carry IPv6 over IPv4 networks, which in turn means that our networks are not limited by the diminishing pool of IPv4 addresses. In addition, our support personnel are IPv6 savvy today.
