Constructors

DNSEntry

public DNSEntry(String hostname, String ip)

Constructs DNS entry with hostname and IP to which it resolves.

Parameters:

• hostname – the domain name for which this record is valid
• ip – IP address of the machine providing the service.

DNSEntry

public DNSEntry(String hostname, String[] ips)

Constructs DNS entry with hostname and multiple IP to which it resolves.

Parameters:

• hostname – the domain name for which this record is valid
• ips – Array of all IP addresses on which target host provide service.

DNSEntry

public DNSEntry(String hostname, String ip, int port)

Constructs DNS entry with hostname, IP to which it resolves and a default port number used for connections.

Parameters:

• hostname – the domain name for which this record is valid
• ip – IP address of the machine providing the service.
• port – the TCP or UDP port on which the service is to be found

DNSEntry

public DNSEntry(String hostname, String[] ips, int port)

Constructs DNS entry with hostname, IPs to which it resolves and a default port number used for connections.

Parameters:

• hostname – the domain name for which this record is valid
• ips – IP addresses of the machines providing the service.
• port – the TCP or UDP port on which the service is to be found

DNSEntry

public DNSEntry(String hostname, String dnsResultHost, String ip, int port, long ttl, int priority, int weight)

Constructs complete SRV DNS entry.

Parameters:

• hostname – the domain name for which this record is valid
• dnsResultHost – the canonical hostname of the machine providing the service.
• ip – IP address of the machine providing the service.
• port – the TCP or UDP port on which the service is to be found
• ttl – standard DNS time to live field.
• priority – the priority of the target host, lower value means more preferred.
• weight – relative weight for records with the same priority.

DNSEntry

public DNSEntry(String hostname, String dnsResultHost, String[] ips, int port, long ttl, int priority, int weight)

Constructs complete SRV DNS entry.

Parameters:

• hostname – the domain name for which this record is valid

• ips – Array of all IP addresses on which target host provide service.
• port – the TCP or UDP port on which the service is to be found
• ttl – standard DNS time to live field.
• priority – the priority of the target host, lower value means more preferred.
• weight – relative weight for records with the same priority.
