IP 位址驗證器 — 常見問題

IPv4 類別之間有何不同?

Class A (1-126): large networks. Class B (128-191): medium networks. Class C (192-223): small networks. Class D (224-239): multicast. Class E (240-255): reserved. Modern networking uses CIDR instead of classful addressing.

這可以驗證 IPv6 位址嗎?

Yes, full IPv6 validation including compressed notation (::), mixed IPv4-IPv6, and all valid IPv6 formats. The tool also expands, compresses, and analyzes the address type.
