Hi Zhang and Thanks a lot ??????!
Excuse me for jumping in.
Please refer to the Ryu-Book for getting started.
For example, "Switching Hub" section describes how to get MAC address of hosts
on Ryu application. I guess you can also get IP address in the similar way.

Thanks,
Iwase

Hi,
Yeah, I can get the IP using Mininet. But I want the Ryu controller learn
the ip/mac adderss of hosts.

Hi,
I think you might need to have a look at the walkthrough on mininet.org. It
might help you a lot.

Hi,
Thanks for your answer.
I also want to know if I use the command 'ping' and generate a ICMP
packet,
how to get IP address from this packet?
Is there any method in Ryu API? I did not find it.

Hello,
You should to gerenerated traffic in hosts, so you can capture packets
and extract IP address.

Hi,
I use Ryu 4.23 and ?0?2Mininet 2.3.0d1 (OVS version is 2.5.2) test
SDN
applications.
My Ryu controller connect to OpenFlow Switches, and some hosts
connect to these Switches.
I want to know how can I get the ip address of the hosts?
Thanks,
YF
