We are using lync server in production,
Domain Controller
Lync Front-End Server on Windows Server 2012r2 standard
SQL 2012 std for monitoring and persistent chat on Windows Server 2012r2
Exchange 2016 on Windows Server 2016
Lync Edge on Windows Server 2012r2
IIS ARR (Reverse Proxy) on Windows 2012r2
We deploy a single Edge server and Create 2 Network interfaces on Edge Server, one to Internal and the other one to External.
On the external interface we configure 3 ip address for access edge service, web conferencing edge service, A/V edge service.
On Reverse Proxy on external we have create 4 external dns record lyncdiscover.<sip.domain>, meet URL, dial-in URL, external web service FQDN.
My intension:
My question.
Question 1. Could I change Lync edge server to use only 1 public DNS for (access edge service, web conferencing edge service, A/V edge service)?
Sure. In this scenario, the three services should be assigned different ports. In general, we use the following configuration: Access Edge: 5061, Web Conferencing Edge: 444, A/V Edge: 443.
For more information about setting up network interfaces for Edge servers, please refer to this article.
Question 2. Could I change reverse proxy server to use only 1 public DNS for (lyncdiscover.<sip.domain>, meet URL, dial-in URL, external web service FQDN.)?
No, all the records are point to the same public IP – Reverse Proxy public IP. But, it needs four DNS records.

Dear SharonZhao,
So, totally can i use only 2 public DNS, one with Edge Server and one with proxy server?
Could you provide me the step by step of migrate ?
@Suy Peang
What do you mean the migrate?
About the public DNS records, you could refer to what Shaw said.
Hello SharonZhao, I mean changing the External DNS records.
@Suy Peang ,
It needs to contact your provider to add external DNS records.
@Suy Peang ,
Do you have any progress on this thread now?

Hi @Suy Peang ,
You can just use 1 public IP for SFB edge server (not recommended), to do this you need to change the port assignments to non-standard values. Refer to this blog:
https://erwinbierens.com/skype-for-business-environment-running-with-just-one-public-ip/
And for RP server, it also can use 1 public IP address, but you need to add the following public DNS records: "lyncdiscover.<sip.domain>, meet URL, dial-in URL, external web service FQDN". These records can point to the same one RP public IP, no need to many public IPs.
