心情: 一般
String domain = "gmail.com";
//查询邮件交换记录
Lookup lookup = new Lookup(domain, Type.MX);
lookup.run();
if (lookup.getResult() != Lookup.SUCCESSFUL){
System.out.println("ERROR: " + lookup.getErrorString());
return;
}
Record[] answers = lookup.getAnswers();
for(Record rec : answers){
System.out.println(rec.toString());
}
//查询域名对应的IP地址
lookup = new Lookup(domain, Type.A);
lookup.run();
if (lookup.getResult() != Lookup.SUCCESSFUL){
System.out.println("ERROR: " + lookup.getErrorString());
return;
}
answers = lookup.getAnswers();
for(Record rec : answers){
System.out.println(rec.toString());
}
运行时需要引入dnsjava的jar包，完！
