Appendix C: IP Address, Subnet and Gateway

This section discusses Communities, Gateways, IP Addresses and Subnet masking
Communities
A community is a string of printable ASCII characters that identifies a user group with the
same access privileges.
For security purposes, the SNMP agent validates requests before responding.
agent can be configured so that only trap managers that are members of a community
can send requests and receive responses from a particular community.
unauthorized managers from viewing or changing the configuration of a device.
Gateways
Gateway, also referred to as a router, and is any computer with two or more network

IP packets among networks on an Internet.

An IP address is a 32-bit value comprised of a network ID and a host ID.
ID identifies the logical network to which a particular device belongs.

IP addresses appear in dotted decimal (rather than in binary) notation.
