  3. Network Tools • IP host reachability test – ping [hostname]. • Measuring the round-trip time for messages sent from the originating host to a destination computer.

  4. NetworkTools • Routing table display • Linux - route • MS Windows – route print • Linux, MS Windows - netstat -r

  5. Network Tools • Diagnostic tool for displaying the route (path) and measuring transit delays of packets across an IP network. • Linux – traceroute [hostname] • MS Windows – tracert [hostname]

  6. Network Tools • Query Internet name servers interactively or non-interactively (DNS lookup utility) • nslookup (Linux, MS Windows)
