For frequent network troubleshooting purposes, do you know a publicly pingable host with an easy to remember IP address (such as 1.2.3.4)?

Answer 1

C:\Documents and Settings\Administrator>ping -a 4.2.2.2

Pinging vnsc-bak.sys.gtei.net [4.2.2.2] with 32 bytes of data:

Reply from 4.2.2.2: bytes=32 time=10ms TTL=246
Reply from 4.2.2.2: bytes=32 time=10ms TTL=246
Reply from 4.2.2.2: bytes=32 time=14ms TTL=246
Reply from 4.2.2.2: bytes=32 time=10ms TTL=246

Ping statistics for 4.2.2.2:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
