Glossary
Below is a glossary of terms commonly used throughout this document.
• DDNS – Dynamic Domain Name System. A Domain Name System assigns a name
to an IP Address – for example, www.google.com
has an IP address of
64.223.167.99. If you type in www.google.com
into your Internet Explorer address
bar, your computer sends a request to a Name System, which looks to the IP
address for Google to bring the information back to your computer.
A Dynamic Domain Name System means that even if the IP address changes (which
happens with most internet providers), the name that you type into your browser
address bar will always find your system. So, typing in
http://mysystem.lorexddns.net
will always find your external IP address, and locate
your system even if your IP address changes.
• DHCP - Dynamic Host Configuration Protocol. Your Router is a DHCP Server, which
will give any device on your network an IP Address when asked. If you have set your
System to have DHCP to ON, when it is connected to your Router it will automatically
get an Internal IP Address.

is a Domain
Name.

telephone company.
• IP Address – Internet Protocol Address. Each device on your network (like a
computer, or your System) will have an individual Internal Address (like
