The following table shows the IP Helper functions with a description of the purpose of each.

Programming element Description

AddIPAddress

This function adds the specified IP address to the specified adapter.

CreateIpForwardEntry

This function creates a route in the local computer's IP routing table.

CreateIpNetEntry

This function creates an Address Resolution Protocol (ARP) entry in the ARP table on the local computer.

CreateProxyArpEntry

This function creates a Proxy Address Resolution Protocol (PARP) entry on the local computer for the specified IP address.

DeleteIPAddress

Use this function to delete an IP address that was previously added using AddIPAddress.

DeleteIpForwardEntry

This function deletes an existing route in the local computer's IP routing table.

DeleteIpNetEntry

This function deletes an ARP entry from the ARP table on the local computer.

DeleteProxyArpEntry

This function deletes the PARP entry on the local computer specified by the dwAddress and dwIfIndex parameters.

FlushIpNetTable

This function deletes all ARP entries for the specified interface from the ARP table on the local computer.

GetAdapterIndex

This function obtains the index of an adapter, given its name.

GetAdaptersAddresses

This function retrieves the addresses associated with the adapters on the local computer.

GetAdaptersInfo

This function retrieves adapter information for the local computer. This function is deprecated in favor of GetAdaptersAddresses.

GetBestInterface

This function retrieves the index of the interface that has the best route to the specified IP address.

GetBestInterfaceEx

This function retrieves the index of the interface that has the best route to the specified IP address.

GetBestRoute

This function retrieves the best route to the specified destination IP address.

GetFriendlyIfIndex

This function takes an interface index and returns a backward-compatible interface index, that is, one that uses only the lower 24 bits.

GetIcmpStatistics

This function retrieves the Internet Control Message Protocol (ICMP) statistics for the local computer.

GetIcmpStatisticsEx

This function retrieves the Internet Control Message Protocol (ICMP) statistics for the current computer.

GetIfEntry

This function retrieves information for the specified interface on the local computer.

GetIfTable

This function retrieves the MIB-II interface table.

GetInterfaceInfo

This function obtains a list of the network interface adapters on the local system.

GetIpAddrTable

This function retrieves the interface–to–IP address mapping table.

GetIpForwardTable

This function retrieves the IP routing table.

GetIpNetTable

This function retrieves the IP-to-physical address mapping table.

GetIpStatistics

This function retrieves the IP statistics for the current computer.

GetIpStatisticsEx

This function retrieves the Internet Protocol (IP) statistics for the current computer.

GetNetworkParams

This function retrieves network parameters for the local computer.

GetNumberOfInterfaces

This function retrieves the number of interfaces on the local computer.

GetPerAdapterInfo

This function retrieves information about the adapter corresponding to the specified interface.

GetRTTAndHopCount

This function determines the round-trip time (RTT) and hop count to the specified destination.

GetTcpStatistics

This function retrieves the TCP statistics for the local computer.

GetTcpStatisticsEx

This function retrieves the Transmission Control Protocol (TCP) statistics for the current computer.

GetTcpTable

This function retrieves the TCP connection table.

GetUdpStatistics

This function retrieves the User Datagram Protocol (UDP) statistics for the local computer.

GetUdpStatisticsEx

This function retrieves the User Datagram Protocol (UDP) statistics for the current computer.

GetUdpTable

This function retrieves the User Datagram Protocol (UDP) listener table.

GetUniDirectionalAdapterInfo

This function retrieves information about the unidirectional adapters installed on the local computer.

IpReleaseAddress

This function releases an IP address previously obtained through Dynamic Host Configuration Protocol (DHCP).

IpRenewAddress

This function renews a lease on an IP address previously obtained through Dynamic Host Configuration Protocol (DHCP).

NotifyAddrChange

This function causes a notification to be sent to the caller whenever a change occurs in the table that maps IP addresses to interfaces.

NotifyRouteChange

This function causes a notification to be sent to the caller whenever a change occurs in the IP routing table.

SendARP

This function sends an ARP request to obtain the physical address that corresponds to the specified destination IP address.

SetIfEntry

This function is used to set the administrative status of an interface.

SetIpForwardEntry

This function modifies an existing route in the local computer's IP routing table. It can also add a new route to the routing table.

SetIpNetEntry

This function modifies an existing ARP entry in the ARP table on the local computer.

SetIpStatistics

This function toggles IP forwarding on or off and sets the default time-to-live (TTL) value for the local computer.

SetIpTTL

This function sets the default time-to-live (TTL) value for the local computer.

SetTcpEntry

This function sets the state of a TCP connection.
