A good thing that CHROME has a built in DNS cache that allows it to speed up loading of pages. This also means that my DNS servers updating is not sufficient at times, i need to clear CHROME's Cache too, here is a way where you could do this :-

chrome://net-internals/#dns

If you really needed this info, guess you are already equipped to take it from here. just enter the above in the Unibox and get going ;-)

Did not work ?? Well your OS still had some records in its cache her's a few more tricks

For windows

ipconfig /flushdns

for the internet ;-)

http://cache.opendns.com/

 Very very useful during the time you set a long TTL value and want to push that site live fast / move a server / have any DNS change
