Show HN: I built a DNS resolver from scratch in Rust

The first thing I look at in new DNS code is whether it’s vulnerable to DNS name compression loops. This code passes the test! However it’s vulnerable to dots embedded in labels: it doesn’t escape bytes properly when converting from wire format to text.

How does one handle dots embedded in a label ? Isn’t that not valid?
