What is normal TTL
TTL is measured in seconds, and the typical default value is usually 12 hours (43200 seconds) or 24 hours (86400 seconds). This means that it takes 12 or 24 hours for new DNS changes to take effect if, for instance, a website moves to a new server or you add a new URL to your server.
What is TTL 255 in ping

What is TTL 64 in Ping
In multicast protocols 64 is used to restrict the packet to the same physical region. 64 is the number of hops that the packet can travel before it is dropped. hard-to-reach hosts that are across many hops of the Internet benefit from a larger TTL on packets.
What is TTL 128 in networking
The TTL is set to 128 by default in Windows and many other operating systems, which means that if a packet hasnt reached its destination after traveling through 128 routers, it will expire and be deleted from the network.
What happens when TTL is 1
The same behavior that a router would display with an IP packet that had an expiring TTL is seen when a labeled packet is received with a TTL of 1, in which case the receiving LSR drops the packet and sends an ICMP message stating that the time limit has been reached (type 11, code 0) to the IP packets originator.5 Jan 2007

What is TTL in DNS settings

- Commit the configuration when you are finished configuring the device.
