I’m lazy and don’t want to remember more than three digits in an IP address or secure all my devices like they’re publicly routable so I’m sticking with IPv4

The possibility to have your packets passed through a shorter route compared to IPv4 packets is worth it imo. I have 280 ms ping to the US and I can cut it down to ~250ms by routing my traffic via certain countries with vpn. I really hope widespread IPv6 deployment would optimize global internet routing so my latency would improve even if just a few ms so I don't need to use VPN to override my route manually.
Maybe a silly question: any ideas why there are shorter routes using IPv6?
- Fewer hops usually required when using IPv6, which means shorter latency.
- Simplified header means less processing time needed to process IPv6 packets, which might improve latency on each hop.
- It also supports multicast, but I'm not sure if it can be used to improve routing and latency.
Thanks! Is there something about the larger area space which means there are fewer hops?

There’s a pretty interesting series on the topic at Tall Paul Tech’s YouTube channel (here’s the most recent: https://youtu.be/WFso88w2SiM). He goes into quite a bit of detail over the course of a few videos about how he handled everything and highlights some of the trials and tribulations with the isp. It’s not a guide per se, but definitely stuff worth thinking through.

The server I have with ovh has ipv6 setup, but only 1 of my VMS on it has an address. It's a lot harder to get your head around then it looks, no NAT. Firewall everything
Absolutely. I use ipv6 so I can directly reach all my servers. For public facing things I put it on an ipv4 address but for my own internal stuff, ipv6.
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?
