IPHelper Functions

The following table shows the IPHelper 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.
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.
