How it works
Paste DHCPv4 options with or without the 0x63825363 magic cookie. Pad and End are handled explicitly and each length is checked before reading data. Common IPv4, timer, message-type, and text options are formatted; unknown options stay raw hex. Option overload into BOOTP fields is outside this options-only input.
