[Enrico Gagliano < >]

*Buona sera a tutti,

come suggerito dagli esercitatori, pubblico la risposta alla mia domanda di oggi a lezione 
sul broadcasting del DHCPDECLINE.*

Droms                       Standards Track                    [Page 39]

RFC 2131          Dynamic Host Configuration Protocol         March 1997


 

4.4.4 Use of broadcast and unicast

  The DHCP client broadcasts DHCPDISCOVER, DHCPREQUEST and DHCPINFORM
  messages, unless the client knows the address of a DHCP server.  The
  client unicasts DHCPRELEASE messages to the server.  Because the
  client is declining the use of the IP address supplied by the server,
  the client broadcasts DHCPDECLINE messages.

4.3.3 DHCPDECLINE message

  If the server receives a DHCPDECLINE message, the client has
  discovered through some other means that the suggested network
  address is already in use.  The server MUST mark the network address
  as not available and SHOULD notify the local system administrator of
  a possible configuration problem.
