Assigning static IP address to a new device doesn’t work.

[jasonz1121]

I have got a new Mac mini that I want to assign the ip address of the old one to it. I deleted the reservation of the old Mac mini and created a new one. But the new Mac mini was never assigned with the ip. This issue applies to all devices. It seems like the only way to solve the issue is to reset the network which is ridiculous.

Just got Google Fiber myself and ran into a similar issue. I have a Windows box which needed a Static IP for serving Plex media, an address which is just outside of the DHCP range I created. The Device just never seemed to come available in the app dialog where I needed to assign the IP in the app. Later it did appear in the listing, and I was able to assign it the static IP desired. The oddity was that I had already set-up the box with the IP directly, yet the router refused to provide it Internet access. I believe just trying to use the machine, or ping things "woke up" the router's Device listings, so eventually it appeared and I was able to set the IP in the Nest app. A similar article here on Port Forwarding troubles suggested a similar issue, so they needed to run a continuous Ping command from that machine to get the router to "see" it.

What a painful app, my old Linksys Router allowed me to simple enter in the desired addresses. I think the Google app is trying to be like Apple software, perfect and clean and works for the mass majority of users who have no special requirements or understand networking.

Google routers, like any other router, assign, or lease, a device an IP address whenever the request is made by the device. Periodically before the lease expires, the router and the device have a short "conversation" and the device (not the router) determines if it wants to keep the IP address it has or request a new one; typically the device just wants to keep the old one. This keeps going until the device disconnects, a lease timeout occurs (usually configurable only on more advanced routers), network reboots (can get same IP depending on connected device settings), or the device drops the old IP and requests a new one (called release & renew).

If you want to reassign your new Mac Mini the newly assigned IP via release & renew follow the below:

Renew your IP address from the DHCP server on Mac (via Mac settings)

How to Renew a DHCP Lease on a Mac (settings and terminal instructions)

If it is to do multiple devices, you will need to restart the network and possibly a few devices too; it takes around 5 minutes or so to complete.
