Restrict admin access using DDNS/DNS host names and other conditions. Extends IP-Geo-Block plugin.

== Description ==

Restrict client login/admin access using domain names (D/DNS, reverse DNS and other). Extends IP-Geo-Block plugin.

= Features =

* **DDNS/DNS Host Names:**
  When your client Host has DNS or Dynamic DNS name, then resolved host name is automatically added to IP Whitelist of IP-Geo-Block.

  Use case 1): 
  If your client host has changing IP (Dynamic DNS)  or you do not want to enter IP number into Whitelist (classic DNS), then configure DDNS-4-Admin by entering your client Host Name. Optionally disable IP-Geo-Block country codes by entering 'YY'.

  Use case 2): 
  To allow login/admin access from client host name in not-allowed country, configure DDNS-4-Admin by entering that client  Host Name (DNS)

* **DDNS/DNS Lookup Caching:**
  Allowed client IP numbers are cached.  Enter maximum time in sec to keep DNS resolved IP numbers cached.

* **Reverse-DNS Host or Network Name:**
  When your client Host has Reverse Host Name (i.e. set by your ISP) then login/admin access to client Network or Host is allowed by matching reverse lookup of Host Name.
  Attention: Reverse host name is usually different than DNS host name

  Use case: 
  In a large country IP-GEO location may not be restrictive enough. Then use this filter to restrict client hosts to your ISP or IP network. Optionally disable IP-Geo-Block countries by entering YY as Whitelist country code.

  ie: 'my.work.pc.example.com' 
    Matches host with '*my.work.pc.example.com' reverse name
  ie: '.example.com' 
    Matches all hosts with reverse name ending with '.example.com'
    ie: www.example.com, user.example.com, my.work.pc.example.com etc.
  ie: '.adsl.isp.provider.example.net' 
    Match only clients from your adsl provider with reverse name
    ie: 12.43.55.66.adsl.isp.provider.example.net

* **Reverse-DNS Lookup Caching:**
  Allowed client IP numbers are cached by IP-Geo-Block plugin.

  Yes.
