What is mean of ping and what is mean of ttl and times?

Ping is a small tool that you can find in a command prompt of any windows machine. It is invaluable when it comes to networks and networking. If there is any one tool you couldn't work without, its ping. So what does it do. It sends a message to a computer anywhere on the network/internet, and if the computer is connected you will get a response. If the computer is not connected to the network/internet you wont get a response. TTL is its 'Time to live'. Say there is a computer on the other side of the network. For the ping to reach it, it might have to go through a router, then through a server and then onto another router and then it gets to the destination. If this is the case it needs 4 hops, one hop for each previously mentioned device. Now if i say i only want the TTL to be 3. That means it will only get to the third hop and that's it. If I say I want the TTL to be 6 then it will get there- because it only takes 4 hops to get to the machine. Usually for most users, you'd be better off leaving the TTL field alone.

What is PTR record?

A PTR record is essentially the opposite of an A record. A records resolve names to IP addresses. PTR records resolve IP addresses to names. A record = give me a name I'll give you an IP PTR record = give me an IP I'll give you a name Try it out in windows: ping "www.yahoo.com" Here is what I got: ------------------------------------------------------------------------------------- F:\>ping www.yahoo.com Pinging www-real.wa1.b.yahoo.com [69.147.76.15] with 32 bytes of data: Reply from 69.147.76.15: bytes=32 time=14ms TTL=53 Reply from 69.147.76.15: bytes=32 time=11ms TTL=53 Reply from 69.147.76.15: bytes=32 time=65ms TTL=53 Reply from 69.147.76.15: bytes=32 time=12ms TTL=53 --------------------------------------------------------------------------------------- now do a "ping -a IP-ADDRESS" which will spit you back the name attached to that IP ---------------------------------------------------------------------------------------- F:\>ping -a 69.147.76.15 Pinging f1.www.vip.re1.yahoo.com [69.147.76.15] with 32 bytes of data: Reply from 69.147.76.15: bytes=32 time=19ms TTL=53 Reply from 69.147.76.15: bytes=32 time=88ms TTL=53 Reply from 69.147.76.15: bytes=32 time=12ms TTL=53 Reply from 69.147.76.15: bytes=32 time=46ms TTL=53 Ping statistics for 69.147.76.15: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 12ms, Maximum = 88ms, Average = 41ms ------------------------------------------------------------------------------------------- Your accessing PTR records to do this. ... and just so you beileve me try a "ping 69.147.76.15" and check the results FYI: if your doing a ping -a to an intranet host you need to configure reverse lookup for it to work properly.

What do the parameters reported back by ping of time and TTL represent?

When you ping an ip address you receive a return from your 'echo request' you can get a multitude of response depending on which 'switches you use' by default windows/DOS returns bytes transmitted time - in milliseconds - the transmission took RTT = round trip time TTL = Time To Live (max 255)
