For quite a while I’ve been wondering if there was a limit of how many aliases I can add to Google Apps and I wasn’t able to find it anywhere in Google Help or other blogs via google search.

To flush or reset DNS on a Mac OS X type the following into terminal and run:
dscacheutil -flushcache
If you have older Mac OS X, this might work for you:
lookupd -flushcache
To flush DNS on any Windows version, click start > Run and type in command:
ipconfig /flushdns
Hope this fixes your DNS issues.
