> > ### How Does the Licensing Method Work?

> > Your license number is issued for both your host name AND your IP Address.

> > This means that you can run PowerWeb Server++ on any server with the host name that you registered, regardless of its IP Address

> > OR,

> > Alternatively you can run PowerWeb Server++ on any server with the IP Address that you registered, regardless of its host name.

> > ### Changing IP Addresses or Host Names

> > A network administrator can move the server to a different subnet, thereby changing its IP Address, but keeping the host name the same. PowerWeb Server++ will continue to run on the same license number, because the host name has not changed.

> > ### This is What Ours Looks Like:

> > Configuration | Server IP Address | Host Name and Domain
> > --- | --- | ---
> > External Server | 196.7.0.66 | www.compusource.co.za
> > Internal Server | 192.168.0.1 | www.internal
> > Local Server | 127.0.0.1 | localhost

> > ### Local Servers

> > Local Loopback, Dynamic SLIP or Dynamic PPP IP Addresses.

> > The local loopback IP Address 127.0.0.1 and the host name "localhost" is automatically configured when you want to use the server on a standalone machine, or if you have a dynamic SLIP or PPP IP Address assigned by your Internet Service Provider.

> > ### External Servers

> > LAN With Internet Access

> > You should license PowerWeb Server++ for the IP Address of the primary LAN adapter of the machine on which the server will run. This will enable all users on the Internet to access your server.

> > ### Internal Servers

> > LAN Without Internet Access

> > You should license PowerWeb Server++ for the IP Address of the primary LAN adapter of the machine on which the server will run. This will enable all users on your private sub-network to access your server.

> > Note for Network Administrators: it is advisable to allocate IP addresses on your internal LAN according to the specifications of RFC1597 to avoid any potential conflict with the Internet.
