I need more options for 'without multicast' ?

[naeoc]

I saw this sentense below, (ASDK Doc. page 15, about json configure, 'network discovery')
'Senders however will avoid using mDNS when a discovery server is configured allowing you to run entirely without network multicast if you desire.'

When I want the sender to avoid using mDNS,
What's the whole configuration factors for 'configured allowing you to run entirely without network multicast if you desire.' ?

Might be like below? or I need more options for 'without multicast (or with unicast)'?

"rudp": {
    "send": {
        "enable": true
    },
    "recv": {
        "enable": true
    }
},

"multicast": {
    "send": {
        "ttl": 1,
        "enable": false,
        "netmask": "255.255.0.0",
        "netprefix": "239.255.0.0"
    },
    "recv": {
        "enable": true
    }
},

"tcp": {
    "send": {
        "enable": false
    },
    "recv": {
        "enable": false
    }
},
"unicast": {
    "send": {
        "enable": true
    },
    "recv": {
        "enable": true
    }
},
