They appear as node but seems not to have snmp activated. The only service detected \
are ICMP and HTTPS.
As far as i know address with a subnet mask of for example /16 may contain devices \
with address containing 0 and 255.
I tried to ping the weird addresses and indeed they respond... Out of 49 sites being \
monitored, only 28 got this issue.
I guess a site visit could help solving this mistery.

Subject: Re: [opennms-discuss] Question on IP addresses
Are those odd addresses appearing in OpenNMS as interfaces on one device per location \
or as multiple nodes, one for each odd address? Does OpenNMS have permission to query \
the devices with SMNP?

wep page which is the remote access to the device (172.16.A.1). I don't have access \
to these devices though.
As far as i know, the sites were designed in such a way that devices within \
172.16.A.0 - 255 belong only to site A and so on...
Can someone help me to see clearer ? Thanks.
