IPv6-Aware and Legacy WPAD helper functions

The following tables explain the differences between the new WPAD helper functions and the legacy WPAD helper functions. The new functions are marked with an asterisk.

Functions	Input	Output	Reason for Change
dnsResolve	Host	IPv4 address	Ex function will return a list of IPv6/IPv4. Necessary since IPv6 or IPv4 addresses can have multiple unicast addresses for a single interface.${REMOVE}$
dnsResolveEx*	Host	List of IPv6/IPv4 addresses

 

Functions	Input	Output	Reason for Change
isResolveable	IPv4 host	TRUE / FALSE	The Ex function will return TRUE if a host can resolve to an IPv6 or IPv4 address. The legacy function only returns TRUE if the host resolves to an IPv4 address.${REMOVE}$
isResolveableEx*	IPv6/IPv4 host	TRUE / FALSE

 

Functions	Input	Output	Reason for Change
myIPAddress	none	IPv4 address	Ex function will return a list of IPv6/IPv4. Necessary since IPv6 or IPv4 addresses can have multiple unicast addresses for a single interface ${REMOVE}$
myIPAddressEx*	none	List of IPv6/IPv4 addresses

 

Functions	Input	Output	Reason for Change
isInNet	Host, Dot separated IP address pattern, IP address Mask	TRUE / FALSE	Provide an IP version agnostic way to find if an IP address is in a given subnet. Also, the mask notation in IPv4 is deprecated.${REMOVE}$
isInNetEx*	IP Address IP Prefix	TRUE / FALSE

 

Functions	Input	Output	Reason for Change
sortIPAddressList*	List of IPv6/IPv4 addresses	Sorted List of IPv6/IPv4 addresses	There is no counterpart legacy function because legacy functions only returned a single IPv4 address, therefore there was no need to sort .

 

Functions	Input	Output	Reason for Change
getClientVersion*	none	WPAD engine version number	Currently this function returns version 1.0. We added this function to allow IT administrators to update their WPAD to work with different versions of the WPAD engine without causing breaks to their existent deployment.

 

Note

This functionality requires Windows Internet Explorer 7 or greater.
