Hi, Mike
Can you give me an example on how to use get-next method to get the
indexes?
I found that I can use snmpwalk to get the the host's ip addresses, but
I don't know how it is done(I paste the snmpwalk command below)
$ snmpwalk -v 2c -c public 127.0.0.1 .1.3.6.1.2.1.4.20.1.1
IP-MIB::ipAdEntAddr.127.0.0.1 = IpAddress: 127.0.0.1
IP-MIB::ipAdEntAddr.192.168.132.128 = IpAddress: 192.168.132.128

You don't - you can use get-next from the top of the table and discover the
indexes.

SNMP can run over many different transports. Also, there are purely IP
elements, such as NAT, that may cause you to communicate with a host using an
IP address which is
not on that host.
HTH,
