Networks : Manual DNS Queries

Which TCP/IP utility allows a user to perform a manual DNS query of any DNS database?
1. TRACERT
2. WINIPCFG
3. >>NSLOOKUP
4. IPCONFIG

Explanation : NSLOOKUP is a TCP/IP utility that allows a user to perform a manual Domain Name System (DNS) query of any DNS database. You would use this to verify that DNS name resolution is functioning properly.

WINIPCFG is a graphical utility found in Windows 9x that allows you to get information about your IP configuration. It also allows you to release a Dynamic Host Configuration Protocol (DHCP) lease and request a new one.

IPCONFIG does the same thing as WINIPCFG, but for Windows NT/2000/XP. IPCONFIG can only be run from the command line.

TRACERT is a utility that allows you to trace the path information takes to get from one machine to another as it moves from network to network.
