As a networking noob: what are the benefits to having/using an IPv6 stack? I realize that eventually we all have to move to IPv6, but any point in being early on it?

IPv6 is pretty much identical to IPv4 in terms of functionality.

The biggest difference is that there is no more need for NAT with IPv6 because of the sheer amount of IPv6 addresses available. Every device in an IPv6 network gets their own public IP.

For example: I get 1 public IPv4 address from my ISP but 4,722,366,482,869,645,213,696 IPv6 addresses. That’s a number I can’t even pronounce and it’s just for me.

There are a few advantages that this brings:

Any client in the network can get a fresh IP every day to reduce tracking

It is pretty much impossible to run a full network scan on this amount of IP addresses

Every device can expose their own service on their own IP (For example: You can run multiple web servers on the same port without a reverse proxy or multiple people can host their own game server on the same port)

There are some more smaller changes that improve performance compared to IPv4, but it’s minimal.

  Well this certainly has me intrigued!

  The no NAT thing really messed with my brain and was probably the hardest thing to overcome for me.

I love moving to ipv6. Hard to learn and had roadblocks but now that it’s set up works fine. Does it matter no but just nice to know I have it figured out.
