已经无法正常发包，logger无发包记录。

目前的RevSuitDNS及POC9是用${jndi:dns://xxx.dnsFlag.domain}/yyy}的方式，还是依赖域名；如果改成${jndi:dns://domain/dnsFlag.XXX}的方式domain指定为ip，用dnsFlag.XXX来作为检测，可以去除域名依赖，最终exp为${jndi:dns://1.2.3.4/dnsFlag.xxx/yyy}。我小改了一下，只需要修改三行代码。

作者可以看看是否可行

public class Ceye implements IBackend {
    OkHttpClient client = new OkHttpClient().newBuilder().
            connectTimeout(3000, TimeUnit.SECONDS).
            callTimeout(3000, TimeUnit.SECONDS).build();
    String platformUrl = "http://api.ceye.io/";
    String rootDomain = "xxx.ceye.io";
    String token = "xxxx";

public Log4j2Scanner(final BurpExtender newParent) {
     this.parent = newParent;
     this.helper = newParent.helpers;
     this.pocs = new IPOC[]{new POC1(), new POC2(), new POC3(), new POC4(), new POC11()};
     this.backend = new Ceye("xxx.ceye.io", "xxxx");
     if (this.backend.getState()) {
         parent.stdout.println("Log4j2Scan loaded successfully!\r\n");
     } else {
         parent.stdout.println("Backend init failed!\r\n");
     }
 }

这样配置会导致打包失败，如果我直接在Log4j2Scanner中使用this.backend = new Ceye();可以打包，但收不到bp警告

Hello!

I've added the .jar file to my Burp Extensions extender tab and I get this following error:

initDomain failed: www.dnslog.cn: No address associated with hostname
