How do you distinguish a DNS problem from a network problem?..

Answer / rajamurthy

It is evident by now, that DNS is a critical component of
Internet networking. When it works well, the Internet will
be easier to use than the telephone. When there are
problems, it may appear to you that the whole Internet is
broken. Knowing a little about how DNS works can help you
describe problems when you are talking to technical support
staff.
