If it means "hostname," then the short answer is: Yes. But it depends greatly on what operating system you use. For UNIX, take a look at the man page for the nslookup command. For VM or MVS, check out the help files for NSLOOKUP or DIG. They are part of the TCP/IP program product. For other operating systems, you should probably contact your system support personnel. If "description" means something else, then the short answer is: No. But it depends on what specific information you're looking for. Feel free to let me know if any of this isn't clear.
