Build DNS packets from structured fields
Use this DNS packet generator to compose domain name queries and responses from structured values. The generated bytes can be copied as Hex or Base64, downloaded as BIN, and sent to the DNS parser for verification.
01Choose a DNS message profile when a template is available, or switch to Field sequence to arrange typed values manually.
02Numeric fields support explicit byte order where applicable; text, Hex, and Base64 fields preserve the exact bytes you enter.
03Generated output is intended for protocol tests, parser fixtures, interoperability checks, and controlled packet analysis.
Frequently asked questions
What can I generate for DNS?
You can compose domain name queries and responses with the available DNS profile fields, then export the resulting application-layer bytes as Hex, Base64, or a binary file.
Can I verify the generated DNS packet?
Yes. Use Verify in parser to open the matching DNS parser with the generated bytes preloaded.
