7TCP/IP Network Basics
Static DNS Naming
In contrast to automatic DNS name resolution, Static DNS naming does
not require any host functionality to support dynamic methods of
hostname resolution. Static DNS Naming
uses a seven-step process to
resolve an IP address to a specified hostname. TCP/IP completes each
step in the sequence shown before returning an error message. See your
instrument’s User’s Guide to determine if your instrument supports
Static DNS Naming.

Static DNS Naming
Local Host (HOSTNAME Utility)
Checks to see if the name of the host you
are using is the same as the name you are
trying to resolve.
HOSTS File
ASCII text file that contains host names
and/or aliases and associated IP addresses.
DNS (Domain Name Service)
Method for linking all host names and IP
addresses on the Internet. A linked and
distributed set of DNS databases containing
host names and IP addresses.
NetBIOS Name Cache
A list of recently resolved NetBIOS names
to IP addresses that is stored temporarily in
local host RAM.
WINS (Windows Internet Naming Service)
A database of all NetBIOS names and IP
addresses that register with the WINS server
or have been entered manually by an
administrator.
Broadcast
TCP/IP sends a broadcast message to all
hosts on the local network (up to the router),
requesting a response from the host it is
trying to find.
LMHOSTS File
An ASCII text file that contains IP addresses
and associated NetBIOS names. This file
cannot include aliases.
Error Message
If all steps fail to provide name resolution,
an error message is returned.
