What I learned from making a DNS client in Rust

• dns-packet

  1 1 10.0 Rust

  Parse DNS packets

I made one too https://github.com/ccouzens/dns-packet

The differences:

I followed this guide rather than the RFCs https://github.com/EmilHernvall/dnsguide/blob/master/chapter...

Mine isn't as polished. The command line parsing and output is more thrown together.

I hardcoded the packet identifier (it's not production code, and I'm only looking up one at a time).

I didn't use any bit manipulation libraries. I can see they would help because DNS packets don't line up their information with the byte boundaries.

• SPCDNS

  An easy to use DNS library with C and Lua bindings

When I wrote my DNS parser [1], I set a follow limit. I'm not sure how viable it would be to limit the pointers to earlier in the packet would be.
