I'm looking for advice on haveing some boxes to have both dynamic and

Why use a static IP at all? We have often enough seen people use static
addresses for the wrong reasons.


As I understand it, the OP wants to use DHCP static leases.


No.

I need this for when move put a box on someone else's network.
So I don't have any control over the dhcp server.


Then set an fix IP on dhcp client (dhclient ...) and remove it when you
don't need it.

Basically, you set the dhcp client to have a static address or let the
client get a lease from a dhcp server.


I'm trying to reduce the amount of work I need to do when I show up and
discover there is no dhcp server.

Example locations: university, coffee shop, convention center, office
meeting room.   In all cases I am a guest for a few days.


I'm pretty sure that all of those places provide dhcp services.

Regardless of the client you are using, there is always a way to have a
script/hook/... that will help you fallback to a static address.




Why do you need dnsmasq into the mix?


I don't - I am just working on client config.


Don't forget that Dnsmasq is a server, that would be lovely if you could
in future state clearly that your question is off topic (OT) in your
subject line.
