5.6 Technical Reference
The following section contains additional technical information about the MAX-
207HW2R features described in this chapter.
5.6.1 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, computers on
a LAN share one common network number.
Where you obtain your network number depends on your particular situation. If
the ISP or your network administrator assigns you a block of registered IP
addresses, follow their instructions in selecting the IP addresses and the subnet
mask.
If the ISP did not explicitly give you an IP network number, then most likely you
have a single user account and the ISP will assign you a dynamic IP address when
the connection is established. If this is the case, it is recommended that you select
a network number from 192.168.0.0 to 192.168.255.0 and you must enable the
Network Address Translation (NAT) feature of the MAX-207HW2R. The Internet
Assigned Number Authority (IANA) reserved this block of addresses specifically for
private use; please do not use any other number unless you are told otherwise.
Let's say you select 192.168.1.0 as the network number; which covers 254
individual addresses, from 192.168.100.1 to 192.168.1.254 (zero and 255 are
reserved). In other words, the first three numbers specify the network number
while the last number identifies an individual computer on that network.
Multicast You do not have to enable multicasting to use RIP-2M. (See RIP
Version.)
Select which version of IGMP the MAX-207HW2R uses to support
multicasting on the LAN. Multicasting sends packets to some computers
on the LAN and is an alternative to unicasting (sending packets to one
computer) and broadcasting (sending packets to every computer).
• None - The MAX-207HW2R does not support multicasting.
• IGMP-v1 - The MAX-207HW2R supports IGMP version 1.
• IGMP-v2 - The MAX-207HW2R supports IGMP version 2.
Multicasting can improve overall network performance. However, it
requires extra processing and generates more network traffic. In
addition, other computers on the LAN have to support the same version
of IGMP.
