Unknow IPs outputed from /var/log/message (102.x.x.x)

1096534Jul 22 2015 — edited Jul 22 2015

From customer's DB server (/var/log/messages),below messages outputed , there are no IPs of 102.xx.xx.xx in customer's environment,

what are these IPs used for?

Are these IPs encoding into somewhere for Exadata?

How to clean the routing information of these IPs?

* 172.18.5.7 and 172.18.5.8 are IB/IF on DB node exa04db4m.
