In Asp.Net Core core how to I get the web site's IP address?

In web forms if I needed to obtain the website server's IP address (say for logging) I could obtain it from request.ServerVariables["LOCAL_ADDR"]

How can it be obtain in Asp.Net Core when running in Kestral behind IIS or IIS Express?

This works for any type of apps asp.net or console only

Dns.GetHostEntry(Dns.GetHostName()).AddressList

or 

from if in NetworkInterface.GetAllNetworkInterfaces()
where if.OperationalStatus == OperationalStatus.Up
from address in if.GetIPProperties().UnicastAddresses
select address

You can also use IHttpContextAccessor class in .net core to get client's ip address

I found solution at this url How to get client ip address in .net core 2.x, is simple small code which gives ip address.

This is what worked for me using .net core 2.1

Adjust the regex to your needs. My prod web servers are in the 10.168.x.x range. my dev machine is in the 10.60.x.x range.

if(String.IsNullOrEmpty(localIpAddress))
{
    var ips = await System.Net.Dns.GetHostAddressesAsync(System.Net.Dns.GetHostName());

    string rgx = (env.IsDevelopment()) ? @"10{1}\.60{1}\..*" : @"10{1}\.168{1}\..*";
    var result = ips.FirstOrDefault(x => {
        Match m2 = Regex.Match(x.ToString(), rgx);
        return m2.Captures.Count >= 1;
    });
    localIpAddress = result.ToString();
}

Although in the end I ended up just using System.Net.Dns.GetHostName() because I didn't really need the IP address.

You can use HttpContext.Features.Get<IHttpConnectionFeature>() - docs:

var httpConnectionFeature = httpContext.Features.Get<IHttpConnectionFeature>();
var localIpAddress = httpConnectionFeature?.LocalIpAddress;
