What is good TTL in Ping?
Here’s a relevant quote from the ping manpage: TTL DETAILS The TTL value of an IP packet represents the maximum number of IP routers that the packet can go through before being thrown away.
The current recommended default time to live (TTL) for the Internet Protocol (IP) is 64..
What is the lowest TTL setting?
TTL is set in seconds, and the lowest value possible is 600 seconds (10 minutes). The highest possible value is 86400 seconds (24 hours). If you leave the field empty, the default value is 3600 seconds (1 hour).
What is TTL 64?
Time To LiveTTL is Time To Live. Each hop decrements this field by one, and if it reaches 0 it is dropped (usually this happens only in loop situations). This makes sure that data packets are not congesting a network if there is a IP routing loop present. … 64 is the number of hops that the packet can travel before it is dropped.
What is TTL measured in?
It’s measured in seconds so one hour would equate to the TTL being set at 3600 seconds. The TTL is automatically set to 86400 seconds (24 hours) when you create a new record for your domain names.
What is the default TTL value in Windows?

How do you set TTL on Ping?
8.8 and press Enter. Observe the results. Then repeat the ping command, each time increasing the TTL (-i) parameter by one until the ping is successful again. The first TTL count which results in success indicates the number of routers or “hops” between your computer and Google’s public DNS server.
What does TTL mean in CMD?
Time-to-liveTime-to-live (TTL) is a value in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded. In IPv6 the TTL field in each packet has been renamed the hop limit.
What is a good TTL?
Generally, we recommend a TTL of 24 hours (86,400 seconds). However, if you are planning to make DNS changes, you should lower the TTL to 5 minutes (300 seconds) at least 24 hours in advance of making the changes. After the changes are made, increase the TTL back to 24 hours.
What is the purpose of TTL?
The purpose of the TTL field is to avoid a situation in which an undeliverable datagram keeps circulating on an Internet system, and such a system eventually becoming swamped by such “immortals”.
How is TTL value calculated?
TTL or Time to Live is a DNS record setting that determines how long a DNS resolver should remember (cache) the DNS query before it expires. To see TTL on Linux, you need to use “dig” command. Use dig + nocmd + noall +answer +ttld for a given domain name.
What is TTL full form?
TTL – transistor-transistor logic, Time to Live or through-the-lens. By – Webopedia Staff. (1) Short for transistor-transistor logic, a common type of digital circuit in which the output is derived from two transistors. The first semiconductors using TTL were developed by Texas Instruments in 1965.
What is extend TTL value?
Spoof LAN TTL value option allows to send packets to the Internet with the fixed TTL field in IP packet header whereas Expand TTL Value option influences traffic in the opposite direction, allowing not to discard those packets which TTL shall be set to zero when passing through a router.
What is a TTL of 14400?
Time to Live (TTL) is the time taken for a domain’s DNS record information to be refreshed. … By default, the TTL is set to 14400 seconds, or four hours.
What is TTL voltage?
A majority of systems we use rely on either 3.3V or 5 V TTL Levels. TTL is an acronym for Transistor-Transistor Logic. It relies on circuits built from bipolar transistors to achieve switching and maintain logic states. … Basically, this means that output voltage of the device driving HIGH will always be at least 2.7 V.
What is TTL 3600?
Time To LiveTime To Live, or TTL for short, is the sort of expiration date that is put on a DNS record. … With a TTL of 3600 seconds, or 1 hour, that means that as a recursive server learns about example.com, it will store that information about the A-record at example.com for one hour.
What is TTL 128 ping?
So, for each switch/router/computer your traffic passes through en route to the destination, that counts as 1 hop, and the TTL to your destination will decrease by each hop. So, when you PING something on your LAN, the TTL will be 128, since all machines on your same subnet (192.168. 1.0/24) are all just 1 hop away.
What is TTL and how it works?
Time to live (TTL) refers to the amount of time or “hops” that a packet is set to exist inside a network before being discarded by a router. TTL is also used in other contexts including CDN caching and DNS caching.
What is TTL connection?
In communication, TTL is Time To Live, which determines how long a packet lives for. If TTL is reached, the packet is discarded. TTL can also mean Transistor-Transistor Logic, which is a type of serial interface. A USB to TTL adapter will allow you to connect your computer to a TTL serial port via your USB.
What does TTL mean in DNS?
time to liveDNS TTL (time to live) is a setting that tells the DNS resolver how long to cache a query before requesting a new one.
How do I change TTL in Windows 10?
AnswersOpen Registry Editor (regedit.exe).From the HKEY_LOCAL_MACHINE subtree, go to the following key: \SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.In the right pane, add the following value: Name: DefaultTTL. Type: REG_DWORD. Valid Range: 1-255.After that, please restart the computer and check the result.
