This PR introduces two new operations to the
Networkingcategory: Decode DNS Wire Format and Encode DNS Wire Format.Summary
It resolves issue #940 by allowing users to decode a binary DNS wire format message (RFC 1035) into readable plaintext (similar to the output of
dig), and conversely, encode plaintext back into binary.This is highly useful for analyzing DNS over HTTPS (DoH) or DNS over TLS (DoT) payloads.
Note: Because these operations work directly with raw binary data (
byteArray), you will typically chain them withFrom HexorTo Hexwhen manipulating hexadecimal string representations in the Input/Output panels.Example 1: Decode
