Network configuration (IPV4)
This page allows you to configure the various aspects of the IP port when it is
used in IPV4 mode. For
IPV6
mode, please see the next page.
MAC address
Media Access Control address – this is the unique and unchangeable code that
was hard coded within your Digital iPEPS unit when it was built. It consists of
six 2-digit hexadecimal (base 16) numbers separated by colons. A section of the
MAC address identifies the manufacturer, while the remainder is effectively the
unique electronic serial number of your particular unit.
Use DHCP
DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks.
When this option is selected, your Digital iPEPS will attempt to locate a DHCP
server on the network. If such a server is located, it will supply three things to
the Digital iPEPS: an IP address, an IP network mask (also known as a Subnet
mask) and a Gateway address. These are not usually granted permanently, but
on a ‘lease’ basis for a fixed amount of time or for as long as the Digital iPEPS
remains connected and switched on.

IP Address
This is the identity of the Digital iPEPS within a network. The IP address can
be thought of as the telephone number of the Digital iPEPS. Unlike the
MAC address, the IP address can be altered to suit the network to which it is
connected. It can either be entered manually or configured automatically using
the DHCP option. When the DHCP option is enabled, this entry is greyed out.
IP Network Mask
Also often called the subnet-mask, this value is used alongside the IP address
to help define a smaller collection (or subnet) of devices on a network. In this
way a distinction is made between locally connected devices and ones that are
reachable elsewhere, such as on the wider Internet. This process helps to reduce
overall traffic on the network and hence speed up connections in general.
IP Gateway
This is the address of the device that links the local network (to which the Digital
iPEPS is connected) to another network such as the wider Internet. Usually the
actual gateway is a network router and it will be used whenever a required
address lies outside the current network.
VNC Port
This is the logical link through which communications with a remote VNC viewer
will be channelled. The default setting is 5900 which is a widely recognised port
number for use by VNC software. However, in certain circumstances it may be
advantageous to alter this number - see ‘Security issues with ports’ for more
details.
HTTP Port
This is the logical link through which communications with a remote web
browser will be channelled. The default setting of 80 is an established standard
for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed
to suit your local network requirements.
IP Access Control
This section allows you to optionally specify ranges of addresses which will or
won’t be granted access to the Digital iPEPS. If this option is left unchanged,
then the default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access from all IP
addresses will be permitted. See
Setting IP access control
for details.
