(<a href="https://news.ycombinator.com/item?id=48542480">via</a>,
<a href="https://lobste.rs/s/cslljn/iroh_1_0_dial_keys_not_ips">via</a>) today as it hit
1.0 and found it a really interesting solution to a problem I knew existed but
had not thought a lot about.</p>
<p>Judging from the comment sections, it seems pretty clear that <em>lots</em> of people
are confused as to exactly <em>what</em> Iroh is. I don’t think their
<a href="https://www.iroh.computer/blog/v1">launch post</a> does their product justice at
all, and their tagline is “IP addresses break, dial keys instead” which sounds
cool, but if you think about it for just a second, you’ll end up with lots of
questions. The biggest one is: “so how is this different from a mesh VPN like
Tailscale, ZeroTier, Netbird, etc.?”</p>
<p>It’s only after reading a lot of developers’ comments on the threads that I feel
I understand: Iroh is aimed at <em>application</em> developers who want to communicate
P2P between machines running their app, while mesh networks are aimed
at <em>network admins</em> who want to connect devices they own/manage together.</p>
