Well-Known Ports

複数のアプリケーションが動作しているＰＣの内部で，トランスポートレベルのサービスを特定する識別子として使用されるポート番号。
この内，０〜１０２３までのシステムポート番号をwell known portsと言い，IANAによって管理されている。
サーバーにおいて開かれているポートを確認することによって，どんなサービスが提供されているかを調べることもできるが，最近は不正アクセスとの兼ね合いもあってあまりお勧めできない。
日常的に知っておくべきポートは，httpの８０番，smtpの２５番，pop3の１１０番，telnetの２３番，ftpの２０，２１番ぐらいだろう。
