Oh, I made a mistake, I added netlify.com and netlify.app to my local DNS server(with dnsmasqd + OpenDNS), so previous post nslookup command is equal:
nslookup dualsub.netlify.app 208.67.222.222
Now I change to my IPS default DNS:
$ nslookup dualsub.netlify.app 202.96.128.166
Server: 202.96.128.166
Address: 202.96.128.166#53
