| LinkLayerAddress | 4 | 접미사가 링크 로컬 접미사입니다. |
| Manual | 1 | 접미사를 수동으로 구성했습니다. |
| OriginDhcp | 3 | DHCP(Dynamic Host Configuration Protocol) 서버에서 접미사를 제공했습니다. |
| Other | 0 | 지정되지 않은 소스를 사용하여 접미사를 배치했습니다. |
| Random | 5 | 접미사가 임의로 할당되었습니다. |
| WellKnown | 2 | 이 접미사는 잘 알려진 접미사입니다. 잘 알려진 접미사는 표준 RFC(Request for Comments) 문서에 지정되어 있으며 IANA(Internet Assigned Numbers Authority) 또는 주소 레지스트리에 의해 할당됩니다. 이러한 접미사는 특수 목적을 위해 예약되어 있습니다. |

설명
IP 주소는 두 부분으로 나뉘어: 접두사 및 접미사. IP 주소는 네트워크 부분을 식별 하는 주소 접두사 및 주소 접미사 호스트 부분을 식별 합니다. 전역 인증 기관에서 할당 된 접두사 및 접미사는 로컬 시스템 관리자가 할당 됩니다.
이 열거는 UnicastIPAddressInformation 클래스에서 사용됩니다. 이 클래스의 인스턴스는에 대 한 유니캐스트 주소 정보를 검색할 때 반환 되는 NetworkInterface 개체입니다.
