Keywords: nameservers, defaultnameservers
When name server lookups are being performed, the nameservers channel keyword may be used to specify a list of name servers to consult rather than consulting the TCP/IP stack's own choice of name servers. The nameservers keyword requires a space separated list of IP addresses for the name servers, as shown in the following example:
nameservers 1.2.3.1 1.2.3.2
The default, defaultnameservers, means use the TCP/IP stack's own choice of name servers.
To prevent name server lookups on UNIX, you can modify the nsswitch.conf file. On NT, modify the TCP/IP configuration.
