Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

Definitely dual stack if you do. The real benefit of IPv6 is that, supposedly, each of your internal devices can have its own address and be directly accessible, but I don't think anyone actually wants all of their internal network exposed to the internet. My ISP provides IPv6, but only a single /128 address, so everything still goes through NAT.
Setting it up was definitely a learning process - SLAAC vs DHCP; isc's dhcpd uses all different keywords for 6 vs 4, you have to run 6 and 4 in separate processes. It's definitely doable, but I think the main benefit is the knowledge you gain.
And the biggest disadvantage of IPv6 is that each of your internal devices has its own address and can be directly accessible from outside. So you need to completely rethink how you do security.
And can be identified/tracked individually by outside entities. In IPv4, a website sees both my device and my kid's device as the same IP. In IPv6 they're different so this just provides more ways for them to track you.
That's the reason for rcf 4941. It randomises the host part of your IPv6 address.
