Auto-IP Addressing
Network devices use automatic IP addressing if they are
configured to acquire an address using DHCP but are unable to
contact a DHCP server. Automatic IP addressing is a scheme
where devices allocate themselves an IP address at random from
the industry standard subnet of 169.254.x.x (with a subnet mask
of 255.255.0.0). If two devices allocate themselves the same
address, the conflict is detected and one of the devices allocates
itself a new address.
Automatic IP addressing support was introduced by Microsoft in
the Windows 98 operating system and is also supported in
Windows 2000/XP/NT.
Private IP Addresses
The following address ranges have been reserved by the Internet
Engineering Task Force (IETF) for private use:
■
10.0.0.0 – 10.255.255.255
■
172.16.0.0 – 172.31.255.255
■
192.168.0.0 – 192.168.255.255
The Router has a default subnet of 192.168.1.0 –
192.168.1.255. 3Com recommends that you use this subnet for
the LAN addresses of your first Device and subsequent ranges
(192.168.2.0 – 192.168.2.255) for the LAN range of other
Devices that you will connect to by VPN.
