Hi all....

when i ping my default gateway or primary DNS server or Secondary DNS Server, i get a line some thing like this
Reply from 117.195.224.1: bytes=32 time=42ms TTL=254

can anybody plz explain this line?

what is bytes=32?
what is that time?
what is that TTL?
ehat is that 254?

time=42ms
that 42ms is not same in each and every line. that number is fluctuating for line to line.
is it necessary to have that time value for every line?

Time is the round trip time
TTL is a value that is decreased by 1 everytime a packet is routed. If the value gets to 0 then an ICMP message is returned to the origin that the packet has expired.(Died in transit)
