type SuffixOrigin

Member nameDescription

The suffix is a link-local suffix.


The suffix was manually configured.


The suffix was supplied by a Dynamic Host Configuration Protocol (DHCP) server.


The suffix was located using an unspecified source.


The suffix was randomly assigned.


The suffix is a well-known suffix. Well-known suffixes are specified in standard-track Request for Comments (RFC) documents and assigned by the Internet Assigned Numbers Authority (Iana) or an address registry. Such suffixes are reserved for special purposes.

IP addresses are divided into two parts: the prefix and the suffix. The address prefix identifies the network portion of an IP address, and the address suffix identifies the host portion. Prefixes are assigned by global authorities, and suffixes are assigned by local system administrators.

This enumeration is used by the UnicastIPAddressInformation class. Instances of this class are returned when you retrieve the unicast address information for a NetworkInterface object.

The following code example displays prefix and suffix information for unicast addresses.
