analyse ping results
(OP)
Hello,
I picked two well known websites to ping and just wondered if anybody could explain what the data is after the IP. why is one 55 and the other 245?
thanks

A good fortune may forbode a bad luck, which may in turn disguise a good fortune.

RE: analyse ping results
A response of 245 would be from a device that uses 255 as its default value for the TTL. This indicates that there are 10 devices between you and the endpoint.
The TTL is 8-bits, so it has a maximum value of 255. As a packet passes through a network node (like a router) that device will decrement the TTL by 1. If the TTL reaches 0, then an ICMP unreachable message is returned by the device that received the packet with a TTL of 1. Traceroute works by sending packets with a TTL of 1, then 2, then 3. Each time it records the source IP address of the ICMP unreachable message.
