As per zabbix_agentd.conf file documentation, the server IP is an optional parameter. This means that if we don't specify this property in the zabbix_agentd.conf file then all server will be able to query the agent. This functionality is not working currently. If we don't specify any value here, the zabbix agent doesn't get up and in the code too, we always do the IP checking un-conditionally.

We don't want to configure the zabbix server ip on multiple machines and hence we need this functionality to be working.
