[BUG] docker容器提示The character [_] is never valid in a domain name

[qlanto224]

Issue Description

Type: bug report
生产使用sentinel的过程中的问题。物理机->虚拟机->容器
sca中配置spring.cloud.sentinel.transport.dashboard虚拟机的ip(192.168.3.2)，可以正确连接，当改成sentinel的容器ip(132.30.0.58)时会出现这个错误。

docker-compose 配置：
version: '3'
services:  
  sentinel:
    image: sentinel-dashboard:1.8.0
    hostname: "sentinel"
    environment:
      - TZ=Asia/Shanghai
    ports:
      - 8858:8858
    restart: on-failure
    networks:
      by_net:
        ipv4_address: 132.30.0.58

networks:
  by_net:
    driver: bridge
    ipam:
      config:
        - subnet: 132.30.0.0/16

同样的docker-compose配置，本地微服务可以在sentinel中识别到，但是生产（虚拟机内的docker容器）提示：

看样子是sentinel是去解析本地网卡时，去解析hosts了，而docker的网卡配置名称是有下划线的，导致解析异常。例如：
