If you use the DOD shell instead of the run dialog box the info will stay on the screen and not disappear. If it scrolls past the top of the DOS window you can just enlarge the window. If you can’t make the window big enough or just want to control the scrolling one page at a time use IPCONFIG \ALL | MORE in the DOS window and it will pause after each page until you hit a key and will display the next page and so on until the info to display runs out.
use START > ALL PROGRAMS > ACCESSORIES > COMMAND PROMPT then type IPCONFIG \ALL
