The next step is to verify the connectivity of the devices and components involved in the network issue. You can use various tools and commands to check the status and configuration of the network interfaces, cables, routers, switches, firewalls, DNS servers, and other devices. For example, you can use:
- ping to test the reachability and latency of a remote host or IP address
- traceroute to trace the path and hops of packets from one host to another
- ipconfig or ifconfig to display the IP address, subnet mask, gateway, and DNS settings of a network interface
- nslookup or dig to query the DNS records of a domain name or IP address
- nmap or netstat to scan the ports and connections of a host or network
By verifying the connectivity, you can identify any broken links, misconfigured settings, or blocked ports that might be causing the network issue.
