    A real mixture. There was OS/2, Windows, AIX, VM/MVS and probably a few
    others. This was in IBM Canada HQ.

    When I started there, everything was static, but there was a gradual move to
    DHCP. There were a lot of people coming and going. Many of the employees
    had ThinkPads.

    I had a static IP, with my first ISP. This was back in the days of dial up

    I agree that routers, servers etc shouldn't have temporary DHCP addresses.
    However, it is possible, though not recommended to permanently assign a
    DHCP address to a device.
