• netstat -r: It displays the routing table, which makes the routes packets take across the network visible.

nslookup: DNS Query Tool

One useful tool for identifying and resolving network-related problems is Windows' robust networking command NSLOOKUP. NSLOOKUP, an acronym for "Name Server Lookup," enables users to obtain details about IP addresses, domain names, and other DNS records by submitting a query to Domain Name System servers. The program offers information about possible network issues by providing details such as the IP address, canonical names, and authoritative DNS server.

Resolving DNS-related problems is one of the main uses for NSLOOKUP. Users can detect errors, fix connectivity issues, or check if a domain can be reached by sending queries to particular DNS servers. Moreover, NSLOOKUP ensures that the proper MX records are set up for email delivery, which helps debug mail server problems.

Through an exploration of NSLOOKUP's complexities, Windows users can improve their ability to troubleshoot networks and expedite the resolution of connectivity issues. Gaining proficiency with this command enables people to effectively handle network problems and navigate the intricacies of DNS, making it a vital asset in the toolbox of an IT specialist.

• nslookup <hostname or IP>: It retrieves and presents the DNS details for the given host.
• nslookup -type = mx <domain>: It obtains mail server (MX) records for the domain in question.

Route: Managing Routing Tables

The Route command is a potent tool for organizing and modifying the routing table in the world of Windows networking. This command's capacity to regulate data packet transit across networks makes it an essential tool for maximizing network efficiency.

Network routes can be customized thanks to the Route command, which enables users to examine and edit the IP routing table. Its simple syntax makes it understandable to even the most inexperienced users. To add, edit, or remove routes, users can access a variety of options by typing "route" into the command prompt.

The current routing table, for instance, can be seen by using the "route print" command. It shows information about interface metrics, destination networks, and gateways. The "route add" command can be used to add a new route, with the target network, gateway, and metric specified.

The Route command is also very helpful in debugging network connectivity problems. Through the identification and correction of routing discrepancies, users can improve the data transfer efficiency between devices.
