RFC 3315 - Final Sections Summary

23. Security Considerations​

Key Security Issues:

  • Malicious DHCP servers
  • Message interception and modification
  • Denial of service attacks
  • Privacy concerns with DUIDs

Recommended Protection Measures:

  • IPsec for server-relay communication
  • DHCP authentication for client-server messages
  • Reconfigure key mechanism
  • Secure DUID generation

24. IANA Considerations​

Registry Requirements:

24.1. Multicast Addresses​

  • FF02::1:2 (All_DHCP_Relay_Agents_and_Servers)
  • FF05::1:3 (All_DHCP_Servers)

24.2. DHCP Message Types​

  • Message type code registry (1-13 defined)

24.3. DHCP Options​

  • Option code registry (initially 1-20 defined)

24.4. Status Codes​

  • Success (0) - Success
  • UnspecFail (1) - Unspecified failure
  • NoAddrsAvail (2) - No addresses available
  • NoBinding (3) - No binding
  • NotOnLink (4) - Not on link
  • UseMulticast (5) - Use multicast

24.5. DUID Types​

  • DUID-LLT (1)
  • DUID-EN (2)
  • DUID-LL (3)
