Network Configuration and Management Utilities

Rating:

Administrators use various utilities to configure and manage networks. Following are some commonly used utilities:

WINIPCFG: WINIPCFG is a Windows 9x Internet Protocol (IP) configuration utility used to display all current TCP/IP network configuration values for a computer running Microsoft TCP/IP. Network configuration values include the current IP address allocated to the computer and other useful data about TCP/IP allocation. This utility is of particular use on networks using Dynamic Host Configuration Protocol (DHCP), allowing users to determine which TCP/IP configuration values have been configured by DHCP.

IPCONFIG: IPCONFIG is a command-line utility used to display current TCP/IP network configuration values, and to update or release the Dynamic Host Configuration Protocol (DHCP) allocated leases. It is also used to display, register, or flush Domain Name System (DNS) names.

NSLOOKUP: NSLOOKUP is a utility for diagnosing and troubleshooting Domain Name System (DNS) problems. It performs its function by sending queries to the DNS server and obtaining detailed responses at the command prompt. This information can be useful for diagnosing and resolving name resolution issues, verifying whether or not the resource records are added or updated correctly in a zone, and debugging other server-related problems. This utility is installed along with the TCP/IP protocol through the Control Panel.

PING: PING is a command-line utility used to test connectivity with a host on a TCP/IP-based network. This is achieved by sending out a series of packets to a specified destination host. On receiving the packets, the destination host responds with a series of replies. These replies can be used to determine if the network is working properly.

TRACERT: TRACERT is a route-tracing Windows utility that displays the path an IP packet takes to reach its destination. It shows the Fully Qualified Domain Name (FQDN) and the IP address of each gateway along the route to the remote host.

PATHPING: PATHPING is a command-line utility that pings each hop along the route for a set period of time and shows the delay and packet loss along with the tracing functionality of TRACERT, which helps determine a weak link in the path.

NBTSTAT: NBTSTAT is a Windows utility used to check the state of current NetBIOS over TCP/IP connections, update the NetBIOS name cache, and determine the registered names and scope IDs.

NETSTAT: NETSTAT is a command-line utility that displays protocol related statistics and the state of current TCP/IP connections. It is used to obtain information about the open connections on a computer, incoming and outgoing data, and also the ports of remote computers to which the computer is connected. The NETSTAT command gets all this networking information by reading the kernel routing tables in the memory.

TELNET: TELNET is a command-line connectivity utility that starts terminal emulation with a remote host running the Telnet Server service. TELNET allows users to communicate with a remote computer, offers the ability to run programs remotely, and facilitates remote administration. The TELNET utility uses the Telnet protocol for connecting to a remote computer running the Telnet server software, to access files. It uses TCP port 23 by default.
