Например вывод в формате json

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "status": "open", "reason": "syn-ack", "ttl": 59} ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "status": "open", "reason": "syn-ack", "ttl": 59} ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "status": "open", "reason": "syn-ack", "ttl": 59} ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "status": "open", "reason": "syn-ack", "ttl": 59} ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "service": {"name": "ftp", "banner": "220 (vsFTPd 2.3.2)\u000a530 Please login with USER and PASS."} } ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "service": {"name": "ftp", "banner": "220 (vsFTPd 2.3.2)\u000a530 Please login with USER and PASS."} } ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "service": {"name": "ftp", "banner": "220 FTP Server ready.\u000a500 AUTH not understood"} } ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "service": {"name": "ftp", "banner": "220 FTP Server ready.\u000a500 AUTH "} } ] },

{ "ip": "xxx.xxx.xxx.xxx", "ports": [ {"port": 21, "proto": "tcp", "service": {"name": "ftp", "banner": "220 ProFTPD 1.3.3a Server (Debian) [::ffff:xxx.xxx.xxx.xxx]\u000a500 AUTH not understood"} } ] },

Необходимо получить список адресов где баннер содержит "220 (vsFTPd 2.3.2)"
