nsdetect - interact with the DNS detection mechanism
nsdetect [ifn [on | off]]


Command nsdetect turns NAT32 DNS Detection on or off for the specified interface. When invoked with no arguments, the current setting for each interface is printed.

When invoked as nsdetect 0, a DNS server address is detected even if the mechanism has been turned off on all NAT32 interfaces.

The NAT32 DNS Detection mechanism monitors incoming DNS responses. If a valid DNS response is received on an Internet-connected interface, NAT32 sets its current DNS Server address to the source IP address of the detected DNS response. Such responses typically arrive after a Windows application does a DNS lookup. The mechanism allows NAT32 to resolve DNS names even if no valid DNS Server address was configured by the user.
