yes, ill admit i didnt do it myself until recently when I didnt want to do yet-another-nat-entry and decided to join modern networking.
should have done it years ago.
What were the biggest pains? What was surprisingly easier than expected?
worrying my head off about security because in the old days IPv6 had some issues esp with bascially putting every device on your network on the public internet with no firewall.
learned that years ago hardware makers started defaulting to blocking all traffic from the outside when ipv6 is enabled. Once I felt comfortable just turning it on I found it pretty easy to grasp esp when the addresses stopped liking like random junk to my eyes.
Once I knew how things worked actually exposing a specific system or port set to the internet was super easy, much easier than NAT + firewall.
with my ISP. v6 unexpectedly brought a new level of privacy we had not had before. When you geolocate the IPs they show up in ISP datacenters all over the country. One day it looks like we are in VA, the next we are coming out of Seattle. We have yet to notice any speed or routing issues. IPv4 and IPv6 play well together though once you turn on v6 you might find yourself turning it on for more vlans than you planned because you want the features!
Thanks! That was really insightful. I guess I'll give it a try some day, for now everything runs in ipv4 and that runs well haha!
don't touch it till you need/want to. I had a system I wanted to expose to the internet on a vlan buried in my network, so ipv6 looked like the quicker of the 2 options. turned out to be right.
