DNS uses UDP instead of TCP.if a DNS packet is lost,there is
no automatic recovery.does this cause a problem and if so,
how is it solved?
Answer Posted / ruchi
Yes, when DNS packets are lost, or a DNS server is unable
to respond, this can cause problems with applications. DNS
handles the resolution of host names to IP addresses.
Without this information, an application cannot initiate a
connection with the appropriate host on the network or
Internet. For example, when you a type in www.yahoo.com
into a web browser, then DNS resolves the address to
66.94.230.38, and the browser attempts an http connection
to this IP address. When you see problems with DNS, you see
the browser "wait" for a response; or, in the case of
Explorer, it will eventually come back and tell you it
couldn't find a particular domain.
