consul dns unfair load balance

#### Overview of the Issue

One backend server's network card is tied to multiple IPs, IP is in different segments of the network.
Consul dns with default config and has a unfair load balance.
There are about 30 TCP connections, most DNS resolvers are directed to the same server except for the native.

#### Reproduction Steps

Steps to reproduce this issue, eg:

backend server:
server1: 192.168.3.99 192.168.2.98
server2: 192.168.3.97

two consul agent:
192.168.3.166
192.168.3.89

dnsmasq config:
server=/consul/192.168.3.166#8600
server=/consul/192.168.3.89#8600

service use 192.168.3.99 to register, but most dns resolvers are directed to 192.168.3.97

Whether additional configuration is required？
