Network Reachability Test

Trace the network path from the NetOz network to any public IP address or hostname

This shows the route from our Adelaide data centre, not from your current location

Note: Private IP addresses (RFC 1918) are not allowed

This check runs from our infrastructure and may log the queried information to improve accuracy and availability. Logs are retained for a short period and are not used for marketing

What is a Reachability Test?

A reachability test checks whether a host or service is accessible over the network by sending probe packets and measuring the response. It combines elements of ping (ICMP echo), TCP connection testing, and HTTP checks to give a comprehensive view of whether a server is online and responding.

This free reachability checker tests connectivity to any host or IP address from our Australian network (AS142205 in Adelaide). Use it to verify your servers are accessible from Australia, diagnose network outages, or confirm firewall rules are correctly configured. Results include response times and hop information.
