DoHの用途
DNS over HTTPS（DoH）は、従来のDNSプロトコル（UDPやTCP）を使用せずに、HTTPやHTTPSを介してDNSクエリとレスポンスを暗号化して送信するプロトコルです。DoHは以下のような用途で使用されます。
dnsdistを使えば自前でDoHやDoTのサーバを構築することができる。
# 自己証明書を作る valid_days=365 openssl genpkey -algorithm RSA -out private.key openssl req -new -key private.key -out certificate.csr openssl x509 -req -days $valid_days -in certificate.csr -signkey private.key -out certificate.crt
dnsdist.confへ以下のように記述する
addDOHLocal('0.0.0.0:55', '/etc/ssl/certs/certificate.crt', '/etc/ssl/private/private.key')
これだけで使うことができるようになる。
digでお試し
新しめのdigならDoHを使うことができる。
+https[=value], +nohttps
This option indicates whether to use DNS over HTTPS (DoH) when querying name servers. When this option is in use, the port number defaults to
443. The HTTP POST request mode is used when sending the query.
If value is specified, it will be used as the HTTP endpoint in the query URI; the default is /dns-query. So, for example, dig @example.com +https
will use the URI https://example.com/dns-query.
こんな感じで実行できる
dig @localhost -p 55 exmaple.com +https
tcpdumpしても平文でやり取りされていないのがわかる
