ZeroTier: is this a good time to use...

I suppose if you only worry about putting servers IPv6 addresses in DNS, then you're probably OK manually handling that - but if you have to do that for endpoints coming and going all the time, then you'll need to give up DHCP ...
If you let ZT assign IP addresses to the devices on the ZT network, those won't change. So when a device "comes and goes" it will always keep the same ZT IP address no matter where it is connected from.
-
I suppose that ZT could be having their DHCP assign static like addresses. So this may not be an issue on ZT.
I was talking a bit more generically for my DHCP server on my LAN - if a laptop stays off beyond my 8 lease, that IP will be assigned to something else.
Have you disconnected something from ZT for say 20 days and ensured when it came back online that it got the same IP?

What's the use case for doing that, though?

Not quite that long, lol. But I have gone a week or two. It does "DHCP" not really true DHCP. Once I connect my laptop up, it associates that laptop with 192.168.100.5, and until I delete the laptop from my list of ZT devices, it will always get 100.5 -- that's the way it appears to work.

What do you mean? This is the default way windows DHCP works. After the IP lease expires, it simply goes back into the pool.

He's talking about generic DHCP on a LAN.

The question is... why would you be using it in a ZT scenario? Why have DHCP for ZT addresses at all? What's the end goal?

Correct - I am talking about my LAN. I'm not assigning IPs to the ZT network adapters.

Oh, I guess I missed something then.

Yeah I don't, never said I did.

I was giving @dafyre an example of when IP's change - my LAN based DHCP will give out the same IP to another device after a leas expires.
What we don't know - does the ZT DHCP follow normal protocols and hand out an IP after a lease expires? or does it assign it for life?

There is no ZT DHCP. That's where the confusion came from. ZT does not use DHCP, so there is no connection to DHCP-like behaviour. Pertino does not either.

What? Then how do addresses get assigned?
Via the client. Remember that the client talks to the server. No need for something like DHCP.

Scott is correct here. If you check a Windows system with ZT installed, and look at the ipv4 properties of the adapter, you will see that by default the IP address & DNS boxes are set to "static" but they are blank.
-
Cool - OK then you can effectively say that the IP assigned on the ZT will never change

In terms of the gateway feature, is it Linux connector + bridged mode?

That is supposed to be the way it works, but I haven't been able to get it to work like that.
If I want it as a "gateway", I just set it up as a router, and add static routes on the physical routers on each site.

that doesn't allow for ethernet level access - definitely not the same thing at all.

Sadly, you are very much correct.
