Yes. You always work with your local node, and active internet connection is required only to sync with other nodes if any..

let multichain = require("multichain-node")({
port: 8081,
host: "localhost",
user: "test",
pass: "test"
});
var mydata={"Name":"Alwin","City":"Btl"};
multichain.getInfo((error,info) => {
if(error){
throw error;
}
console.log(info);
})

throw error;
^
Error: getaddrinfo ENOENT localhost:8081
at Object.exports._errnoException (util.js:1016:11)
at errnoException (dns.js:55:15)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:91:26)
how can i solve it
You are saying that It was working fine when you are in internet, then your multichain configurations should be fine.
Try 127.0.0.1 instead of localhost and check..

I don't believe that you need to have internet for this. As long as your nodes can talk to each other then you are good to go. There are several organizations where access from servers to the internet is strictly restricted.
You disconnect the internet connection and loses the connectivity means your servers are not in the same network and has no connectivity over the LAN. WAN is not needed
