    Freecom Data Tank Gateway 5.10 Port forwarding Port forwarding allows you to forward ports from clients on the local network to any port(s) on the Data Tank Gateway that you select. This makes it possible to access services of the local area network from other networks such as the Internet. Services on certain clients can thus act as servers as they can now be reached via preset ports that no one else is using.

  • Page 128 Freecom Data Tank Gateway Domain Name Server The computer address is difficult to read, which is why a second system is used in the Internet by the name of DNS (Domain Name Server). This translates human-readable names such as www.sharemydisk.com into computer readable names like 82.161.11.206.
  • Page 129 Appendix Netmask The partition scheme that separates the different address classes is used to identify a net- mask attached to the IP address. A netmask is a 32-bit quantity that, in logical combination (using an AND operator) with an IP address, forms the network address. The netmasks for Class A, B and C are for instance 255.0.0.0, 255.255.0.0 and 255.255.255.0.

Although the exact size is unknown, the current estimate is that there are about 100 million hosts and more than 350 million users actively on the Internet. In fact, the rate of growth has been such that the Internet is effectively doubling in size each year.
