2.2.11 DHCPv4 Option Code 15 (0x000f) - Domain Name Option

  • Article

DHCPv4 Option Code 15 is defined in [RFC2132] section 3.17 which specifies the domain name that the client SHOULD use when resolving host names by using the DNS. [RFC1035] provides the specification for domain names, but does not explain how to ASCII-encode a name if the client has a non-ASCII name, and hence the contents of this option are implementation-specific.<21>
