# DNS Enum Specs

This directory contains local copies of [IANA DNS enum specifications](https://www.iana.org/assignments/dns-parameters/).

- `dns-parameters-*.csv` are the enum specs fetched from IANA. These are fetched and used by `examples/update_fbs.rs` to generate `dns_enums.fbs`. The local copies may also be updated using `update_fbs --fetch`.
- `sections.csv` lists the expected enum types across the `dns-parameters-*.csv` files. Used by `examples/update_fbs.rs` to know what files to fetch and what to name their respective enums.
