Member Function Documentation

◆ getAuthoritative()

bool isc::dhcp::Network4::getAuthoritative ( ) const

inline

Returns the flag indicating if requests for unknown IP addresses should be rejected with DHCPNAK instead of ignored.

Returns: true if requests for unknown IP addresses should be rejected, false otherwise.

Definition at line 396 of file network.h.

◆ getMatchClientId()

bool isc::dhcp::Network4::getMatchClientId ( ) const

inline

Returns the flag indicating if the client identifiers should be used to identify the client's lease.
