Accessing the camera from the internet

Using the 'SwannEye Search Tool' you have been able to access the IP camera
from the same network that your computer and IP camera were connected to.
Ideally, you will want to access the camera from a remote location outside your
local network whether that is on the other side of the town or the other side of
the world.
This can be one of the more daunting aspects of accessing devices over the
internet but this section aims to help you through.
10.1.

What are IP addresses

Every device connected to the internet needs an IP address. An IP address is a
number by which the device is identified, a bit like a mailing address for your
house. An IP address is usually in the format of four numbers (each from 0-255),
separated by periods (i.e. 123.123.123.123). If the number is less than three digits ,
the zero is sometimes omitted (i.e.
Google.com for instance has the number 74.125.153.147. If you type this number
into a browser, you will reach Google.com.
These numbers are hard to remember, just like phone numbers are hard to
remember. That's where Domain Name Servers (or DNS) come in. Domain Name
Servers are like Yellow Pages listings for IP addresses. They are computers located
around the world that link a name (like Google.com) to an IP address. When you
type in Google.com into your browser, the name is checked at a DNS server which
tells it what number is linked to that name and where to find it.
Google not only owns the domain name Google.com, but they also own the
number that is attached to it. Therefore, they will always be known by the same
name and the same number. This costs money but is worth it since they intend to
be around for a long time. This type of never changing number is called a static IP
address since it never changes. How does that relate to you?
Note: The IP address we refer to here is the EXTERNAL IP address that the rest of
the world sees. It is also called a WAN (Wide Area Network) public IP address and
is usually assigned by your ISP. The IP address you used from the SwannEye Search
Tool to access your camera is your INTERNAL IP (also called your LAN (Local Area
Network) private IP address. This is usually assigned by your router using DHCP.
123.123.123.8 is the same as 123.123.123.008).
