 ### Remote DHCP resolution
-When gathering various IP address-related metrics, MKTXP automatically resolves IP addresses whenever DHCP info is available. In many cases however, the exported devices do not have this information locally and instead rely on central DHCP servers.

+### mktxp listening socket addresses
+By default, mktxp runs it's HTTP metrics endpoint on any IPv4 address on port 49090. However, it is also able to listen on multiple socket addresses, both IPv4 and IPv6. 
+You can configure this behaviour via the following [system option](https://github.com/akpw/mktxp/blob/main/README.md#mktxp-system-configuration), setting ```listen``` to a space-separated list of sockets to listen to, e.g.:
 ```
-port = 49090 
+listen = '0.0.0.0:49090 [::1]:49090'
 ```
+A wildcard for the hostname is supported as well, and binding to both IPv4/IPv6 as available.
 
 ## Setting up MKTXP to run as a Linux Service
 If you've installed MKTXP on a Linux system, you can run it with system boot via adding a service. \
