查人人中国名人网述职报告的目的:有关TTL的返回值
来源：百度文库 编辑：查人人中国名人网 时间：2024/04/28 16:31:10
每个系统都有默认的TTL返回值。
可是我ping了几个之后发现得到的都不是默认值
例如
C:\>ping 60.208.167.74
Pinging 60.208.167.74 with 32 bytes of data:
Reply from 60.208.167.74: bytes=32 time=933ms TTL=63
Reply from 60.208.167.74: bytes=32 time=841ms TTL=63
Reply from 60.208.167.74: bytes=32 time=1118ms TTL=63
Reply from 60.208.167.74: bytes=32 time=981ms TTL=63
Ping statistics for 60.208.167.74:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 841ms, Maximum = 1118ms, Average = 968ms
TTL为63，有的更离谱。
能告诉我这是为什么么？？？

取决于对方的操作系统，另外也可以因网络路径导致小幅度的变动。
建议用tracert 命令配合使用。
对方通过修改注册表可以修改默认的TTL返回值
