사용 방법
사용 방법
- Enter a valid IPv4 start and end address.
- Choose a maximum output size, then expand the inclusive range.
- Copy the addresses or download them as a TXT file.
Inclusive IPv4 ranges
The expander treats each dotted-quad address as a 32-bit value and walks upward from the start through the end. Leading zeroes are accepted and normalized in the result; the start must not be greater than the end.
Bounded output keeps the page responsive
A configurable maximum prevents accidentally rendering millions of lines in the browser. Expansion stops before creating output larger than the selected address count, and everything is processed locally.
자주 묻는 질문
더 알아보기
Are both addresses included?
Yes. The start and end addresses are inclusive.
Can I expand an entire IPv4 space?
No. The tool intentionally limits the number of generated addresses to keep the browser responsive. Use a dedicated network utility for very large exports.
Does this validate whether addresses are reachable?
No. It only expands the numeric range and does not scan or contact any address.
Can I save the result?
Yes. Copy the newline-separated list or download it as a UTF-8 TXT file.
