Public IP address.
IP addresses have three possible methods of entry on the eyesite 550, although two
are listed in the flow chart.
A public IP address has the format xxx.xxx.xxx.xxx where xxx is a number in the
range 0 to 255.
Example: 62.173.119.215
This number is unique to you, your company, or your broadband line. It is often
obtained when you order a line from your ISP (Internet Service Provider).
Static Addresses (examples 1 & 2)
Where possible specify a fixed or static IP address. This means you can keep the
address and call it with a minimum of complexity.
The address must be manually entered along with the subnet mask and default
gateway. These numbers will be provided by your service provider or network
administrator.
A static address does not usually require a location service as the address can be
called from any line, however a location service may be chosen if required to allow
simpler numbering, or to provide notification of a loss of service.
Dynamic (DHCP) Addresses (examples 3 & 4)
If you cannot get a fixed IP address (known as a static IP address) it is likely that you
will get a dynamic DHCP address (Dynamic Host Configuration Protocol). This is
presented automatically but can change if the equipment is powered down or if
maintenance is carried out at the telephone exchange.
Because this number can change step 3 provides two alternative solutions for locating
an eyesite 550 at any time despite the possibility of an IP address change.
PPPoE Address
A small number of Internet Service Providers (ISPs) support PPPoE (Point to Point
Protocol over Ethernet).
If the eyesite 550 is directly connected to an ADSL line that supports PPPoE, a user
name and password are entered, and if successful, the eyesite 550 is automatically
provided with an IP address, Subnet Mask, and Default Gateway. If you use this
technique this is all you need to (or can) do, so no examples are required.
