Why should you switch to IPv6?

Much has been said about the ease of implementing IPv6, but practice has shown that this is not as easy as it was initially maintained. While the implementation of IPv6 within the backbone of your own network can be relatively simple, so the implementation of IPv6 "on the edge" of the network and the parallel operation of IPv4 and IPv6 causes a lot of problems (and costs) that operators (who should be the most interested in this standard) do not want bear.

The advantage of IPv4 over IPv6 is certainly a much larger address space. Thanks to the transition from 4 to 16 bytes, the address pool will be exhausted not in 10, 20, but in … it is difficult to say how many years, because the pool of IPv6 addresses is 2 to the power of 128. So … 340 282 366 920 938 463 463 374 607 431 768 211 456. That's much more than 4.2 billion …

There are other arguments in favor of IPv6 – such as facilities for hardware builders and programmers thanks to the simplified IP header and the ability to extend the protocol by adding headers. End users will not feel this, but it will significantly affect the work of people strongly associated with the creation of software and devices.

Operators are not willing to quickly switch to IPv6 also for one important reason: in practice, IPv6 needs smaller routing tables. However, when migrating to a higher standard, they must use even larger tables capable of handling both IPv4 and IPv6. This in turn creates further problems and so on and so forth …
