+Configuring Dynamic DNS is relatively simple, but a few things must be considered.
 First you need to find a DNS provider you want to work with, many are free to use but be sure to check and abide by their terms of service.
-In many cases you will need to register a domain name of your own and configure your domain's DNS to point to the (two or more) name servers for your DNS provider.
+In many cases you will need to register a domain name of your own and configure your domain's DNS to point to the (two or more) name servers as instructed by your DNS provider.
 So, while many DNS providers are free of charge, your domain name will have a nominal yearly cost.

 ===== Dynamic DNS Standard Configuration =====
+For the standard case where a single DNS provider is used, this example uses the "HE Free DNS" (Hurricane Electric) provider updating both IPv4 (''A'' record) and IPv6 (''AAAA'' record).
+For the "HE Free DNS" service type, you must first create the ''A'' and ''AAAA'' records for ''dydns.example.com'' (fictitious) using the [[https://dns.he.net/|HE Free DNS]] web portal, and mark those records as dynamic.  Use the generated API key as your password.

 ===== Dynamic DNS Custom Configuration =====
 In most cases the standard configuration (above) will be fine.  But for more advanced situations, multiple providers, multiple IP's, etc. a custom ''/mnt/kd/ddclient.conf'' file can be created.

 The next time you "Restart Dynamic DNS" the custom config will be used, but will work exactly as the standard case, matching the various "DNS Service Type:" menu entries.  You may now make simple edits to the custom ''/mnt/kd/ddclient.conf'' file, maintaining support for all the "DNS Service Type:" menu entries.
-For more complex configurations, you may find that supporting all the "DNS Service Type:" menu entries with the special syntax is too cumbersome, you may define your ''/mnt/kd/ddclient.conf'' without the leading provider syntax, but the "DNS Service Type:" menu selection will be ignored.

+Clicking on the **Dynamic DNS Configuration** button will allow you to edit the ''/mnt/kd/ddclient.conf'' file.
+!!Tip ->!! Macro replacements of ''@FOO@'' variables will still be performed if your custom ''/mnt/kd/ddclient.conf'' contains such entities.
+For example, your custom ''/mnt/kd/ddclient.conf'' may start with the same initial lines of the system template ''/stat/etc/ddclient.conf'':
+  daemon=@DELAY@
+  @USE_WEB@use=web, web=@WEB_STR@
+  @USE_IF@use=if, if=@EXTIF@
+  @USEV6_WEB@usev6=web, webv6=@WEBV6_STR@
+  @USEV6_IF@usev6=if, if=@EXTIF@
+These lines will allow the "DNS Get IPv4 Address" and "DNS Get IPv6 Address:" web interface entries to work as expected.
+You may leave the "DNS Hostname", "DNS Username" and "DNS Password" entries empty if you wish, or use @DDHOST@, @DDUSER@ and @DDPASS@ to pass along any of those web interface fields.
