What is the TTL in ping?
The TTL field, Time To Live, of an IP packet represents the maximum number of IP routers that the packet can go through before being discarded. During normal operation, ping prints the TTL value for every packet it receives.
What is the best TTL in ping?
The TCP/IP specification recommends setting the TTL field for IP packets to 64, but many systems use smaller values (4.3BSD uses 30, 4.2BSD used 15). And to quote RFC 1700: The current recommended default time to live (TTL) for the Internet Protocol (IP) is 64.
How is TTL calculated in ping?
Each time a packet takes another hop, its TTL is reduced by one. The TTL number that ping reports is the packet’s final TTL when it reaches its destination. To find out the number of hops a packet takes, subtract its initial TTL (by default 255) from the TTL reported by ping.
How do you trace route an IP address?
Take the following steps to run a traceroute in Microsoft ® Windows ®:
- Press Windows key + R to open the Run window.
- Enter cmd and press Enter to open a Command Prompt.
- Enter tracert, a space, then the IP address or web address for the destination site (for example: tracert ).
- Press Enter.
What is normal TTL?
How long is TTL? TTL is given in seconds. The typical default value is usually 12 hours (43200 seconds) or 24 hours (86400 seconds).
Is high TTL good?
The higher the TTL, the less frequently caching name servers need to query authoritative name servers. A higher TTL reduces the perceived latency of a site and decreases the dependency on the authoritative name servers. The lower the TTL, the sooner the cached record expires.
What is TTL 126?
The TTL value is an 8-bit field, which means it can contain a value between 0 and 255. For example, if NNM sniffed a server sending a packet with a TTL of 126, it detects that 128 is two hops away. NNM does not know the IP address of the in-between routers.
How do I change my TTL to ping?
To ping with a custom TTL:
- Open a command prompt.
- Type ping 8.8. 8.8 and press Enter.
- Observe the results. The ping request should be successful.
- Type ping -i 1 8.8. 8.8 and press Enter.
- Observe the results.

How do you trace Ping?

- In the command line window that opens, type ping example.com, and hit Enter.
- Once the test is complete, type tracert example.com and hit Enter.
Is low TTL good?
By having a lower TTL, you can ensure that you are receiving the most recent updates in a given timeframe. Your time to live is critical in controlling your resolver caching directly. For example, your DNS resolver will pull a DNS record from its authoritative server every hour.
Apakah TTL merupakan bagian dari Ping?
TTL atau Time to Live adalah bagian dari ping yang menandakan mekanisme pembatasan umur data dalam pengiriman data dalam suatu jaringan komputer, yang biasanya ditampilkan dalam satuan angka bulat. TTL memiliki fungsi dalam program ping untuk membatasi waktu dalam ping dalam jangka waktu tertentu.
Mengapa TTL membatasi waktu dalam Ping?
TTL memiliki fungsi dalam program ping untuk membatasi waktu dalam ping dalam jangka waktu tertentu. Jika dalam satu program ping TTL bernilai 50, maka ada batasan waktu tertentu hingga waktu TTl semakin berkurang dan jika packet data telah melewati banyak router maka makin lama TTL akan habis atau expired.
Apakah TTL adalah batasan waktu untuk membatasi pengiriman paket?
TTL adalah batasan waktu yang diberikan komputer dalam program ping untuk membatasi pengiriman paket data dengan tujuan menandai packet ping harus berakhir dalam satuan waktu tertentu. TTL bisa dibilang satu paket dengan ping karena memang bagian dari program tersebut.
Apakah TTL berfungsi untuk meningkatkan kinerja komputasi?
TTL ini berfungsi untuk mencegah paket data yang beredar secara terus menerus dalam aplikasi komputasi, tak hanya itu, TTL ini juga seringkali digunakan untuk meningkatkan kinerja chaching atau untuk meningkatkan privasi PC. Lalu bagaimana mengartikan reply dari proses ping tersebut?
