 回答:
 
-可以通过系统变量 `elasticjob.preferred.network.interface` 指定网卡。
+可以通过系统变量 `elasticjob.preferred.network.interface` 指定网卡或 `elasticjob.preferred.network.ip` 指定IP地址。
 
-例如指定网卡 eno1:`-Delasticjob.preferred.network.interface=eno1`。
+例如:
+
+1. 指定网卡 eno1:`-Delasticjob.preferred.network.interface=eno1`。
+1. 指定IP地址 192.168.0.100:`-Delasticjob.preferred.network.ip=192.168.0.100`。
+1. 泛指IP地址(正则表达式) 192.168.*:`-Delasticjob.preferred.network.ip=192.168.*`。

 Answer: 
 
-You may specify interface by system property `elasticjob.preferred.network.interface`.
+You may specify interface by system property `elasticjob.preferred.network.interface` or specify IP by system property `elasticjob.preferred.network.ip`.
 
-For example, specify the interface eno1: `-Delasticjob.preferred.network.interface=eno1`.
+For example
+
+1. specify the interface eno1: `-Delasticjob.preferred.network.interface=eno1`.
+1. specify network addresses, 192.168.0.100: `-Delasticjob.preferred.network.ip=192.168.0.100`.
+1. specify network addresses for regular expressions, 192.168.*: `-Delasticjob.preferred.network.ip=192.168.*`.
