Specific desired hostname

[Juan Manuel Zolezzi]

We are testing a control panel solution at Google Cloud, but noticed the hostname is being constantly changed.

This causes some trouble on licensed software installed at the server.

What' the correct way to change this and avoid the automatic change?

We even consdiered recreating the instance but we are not able to use dots at the server's name, so we are a bit confused.

Hello Juan, 

It is possible to reserve a static address for your server, and an easy to accomplish procedure. A static external IP address is an external IP address that is reserved for your project until you decide to release it. If you have an IP address that your customers or users rely on to access your service, you can reserve that IP address so that only your project can use it. It is also possible to promote an ephemeral external IP address to a static external IP address. You may check the "Reserving a Static External IP Address" documentation page for more detail. 

You may use the console, an API call or a gcloud command, at your convenience. If you prefer the console, you may follow these steps: 

1. Go to the Reserve a static address page in the GCP Console.

   GO TO THE RESERVE A STATIC ADDRESS PAGE

2. Choose a name for the new address.
3. Specify whether this is an IPv4 or IPv6 address. IPv6 addresses can only be global and can only be used with global HTTP(S), SSL proxy, and TCP proxy load balancers.
4. Choose whether this IP address is regional or global. If you are reserving a static IP address for an instance or for a Network load balancer, choose Regional. If you are reserving a static IP address for an HTTP(S), SSL proxy, or TCP proxy load balancer, choose Global.
5. If this is a regional IP address, select the region to create the address in.
6. [Optional] Select a resource to attach the IP.
7. Click Reserve to reserve the IP.
