Dear Experts,
In all the projects I have worked I have been given PI server after installation and have been asked to make XYY (eg 100, or 200 or 300) as the client to work on, and accordingly I do post installation on that client.
But we know 001 is the default client on installation.
But recently I have been asked by one basis person, who is working on PI for the first time , if there is any best practice which says not to use 001 as working client? I have seen client as 001 and 200 and 300 too in many clients PI system.
Any input is appreciated 
Thanks.
