「MAC Address 생성기」는 코드, 데이터 및 QR 작업을 위한 브라우저 도구입니다. 입력과 결과는 일반적으로 이 기기에서 처리되며 가입이 필요하지 않습니다.
사용 방법
사용 방법
- Choose a MAC address format and how many addresses to generate.
- Enable locally administered addresses when the values are for private or virtual network use.
- Generate the addresses, then copy or download the newline-separated result.
Choose a common MAC notation
Colon format uses six pairs such as 02:7A:4C:91:3E:B8. Hyphen format uses the same bytes with hyphens, while Cisco dot format groups the address into three four-hex-digit blocks.
Local and private generation
Generation runs in your browser with crypto.getRandomValues. The multicast bit is cleared so the result is an individual address; the local-admin option sets the locally administered bit for private, virtual, or lab use.
자주 묻는 질문
더 알아보기
Are these real hardware addresses?
No. They are random values for testing, documentation, virtualization, and other development uses. Check your network policy before assigning one to a device.
What does locally administered mean?
It sets the second least-significant bit of the first byte, indicating that the address is assigned locally rather than being a globally registered vendor address.
Are generated values unique?
The generator keeps values unique within each result. It cannot guarantee that a value is unused elsewhere on your network.
Does the address leave my browser?
No. Randomness, formatting, copying, and downloading happen locally in your browser.
