I´ve deployed DA EDGE server on 2012 R2 in a LAB enviroment. I don´t have a plublic domain name and PKI infra. So I did a quick deploy using public IP as a name, distributed pre-build policies to a test laptop, changed the connetion from AD LAN to a public internet connection and started testing this out. The problem is, that laptop is has a status "connecting" on a DA connetion for ages. Nothing happends. On event viewer I see some DNS errors, because it cannot register itself into public DNS server.
On my DA server, I did a quick deploy. It has direct NIC to internet and another to corporate LAN (AD). All status is green. I checked this two article, but does not apply to me, all good:

Any tips? Is it possible to do DA with public IP and not with public domain?
