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 it the fullform of TTL in ping utility?
The full form of TTL is Time To Live
Why the ttl change in the same ping?
You have multiple routes between you and your ping target.
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 does TTL expenses mean?
Answer:Most likely 'TTL expenses' means 'Total expenses'. 'Total' has the highest score for the abbreviations that 'TTL' could mean (see link). Since you are probably dealing with accountants, it could also mean 'Time To Laugh'. ;)
Without a browser how do you check that if website is working ok or not on web server?
you can test to see if the server is active by sending a "ping". A ping is mainly used for this and for measuring connection speeds and response (ping) times... if you are using windows 9x or above this is done by going start > run and then typing in the box "command" if that doesn't work, try "cmd" (no quotes). Once you are there, type the following info (replace [servername] with you server's name ie faqfarm.com) ping [servername] your response will look like this: Pinging faqfarm.com [67.15.50.54] with 32 bytes of data: Reply from 67.15.50.54: bytes=32 time=62ms TTL=45Reply from 67.15.50.54: bytes=32 time=64ms TTL=45Reply from 67.15.50.54: bytes=32 time=61ms TTL=45Reply from 67.15.50.54: bytes=32 time=67ms TTL=45 Ping statistics for 67.15.50.54: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds: Minimum = 61ms, Maximum = 67ms, Average = 63ms if the server is online or Unknown host oogaboogawimbletonmegalongurlthatprobablydosn'tedxist.com. if it is offline or down
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)
Can you know ip corresponding to a given URL?
The easiest way is to use the ping function, which is part of Windows and all varieties of Unix. To use ping with Window, you need to open a command window - click start, select Run and enter cmd followed by enter. A command window should open, you can now type: ping <url> Ping sends an echo request packet and displays the response, which will come back as an ip address, for example: C:\Users\Andrew>ping bbc.co.uk Pinging bbc.co.uk [212.58.224.131] with 32 bytes of data: Reply from 212.58.224.131: bytes=32 time=16ms TTL=121 Reply from 212.58.224.131: bytes=32 time=18ms TTL=121 Reply from 212.58.224.131: bytes=32 time=16ms TTL=121
Why when you ping a host in a LAN the TTL value is 128 but if you ping a host in another network the TTL value decreases from 255 to 254 my question is why the TTL value is 128?
The TTL or Time To Live is a value used to make packets eventually die, so they don't end up in infinite loops, clogging the network over time. Certain network devices decrement this value (routers mainly) by one as they process it. When the TTL reaches zero, the packet is discarded. Each Operating System implements its TCP/IP stack differently and starts packets off with the TTL of their choosing (the default TTL of the stack can be changed, but rarely is). Windows is 128 Linux is 64 Cisco is 256 So if your TTL is around 128 (remember the TTL gets decremented by certain devices) you are PROBABLY pinging a windows box. If it's near 256, probably Cisco etc. You can't rely on this information because other network devices can rewrite the TTL in a packet, but it's a decent indication of the OS on the other end, especially if it's a box you own and you aren't going through firewalls etc.
What does this means reply from 192.168.40.183 bytes equals 32 time equals 2ms TTL equals 128?
the IP 192.168.40.183 that you were trying to ping (the computer you were trying to reach) returned 32bytes in 2milliseconds. TimeToLive (of the ping request is 128 milliseconds)
Interfacing of ttl with cmos and cmos with ttl?

What does TTL applies mean?
TTL is a logic family. A logic family is the set of logic gates designed using a specific approach. Or simply speaking, logic family is the way of implementing logic. TTL stands for transistor - transistor - logic. It involves transistors (BJT) to implement logic. TTL applies means TTL logic family is used or can be applied in that specific application.
When you BBM what does a PING mean?
when you bbming someone and you ping theit doesnt mean anything. Idt just means that the get this big loud ping and when the read it it says ping.
