remarks
----------------------------------------------------
Please DO NOT send spam or hack complaints to us where
a trace to the source (but not the Received: headers)
reveals one of:
195.66.224.x, 195.66.225.x, 195.66.226.x, 195.66.227.x,
195.66.228.x, 195.66.230.x,
195.66.236.x, 195.66.237.x, 195.66.238.x, 195.66.239.x\
195.66.244.x ,195.66.246.0/24 & 195.66.254.0/24
As we are not the origin of the spam/hack or the owner of
these routers, we CANNOT usually take any action.
Please DO NOT just e-mail all contacts or we'll all
ignore it.
Complaints go to the ISP at the source network, not us.
---------------------------------------------------
Please note that devices in 195.66.224.0/22,
195.66.228.0/24, 195.66.230.0/24, 195.66.236.0/22,
195.66.244.0/24 ,195.66.246.0/24 & 195.66.254.0/24
are mostly LINX member routers.
We assign IP addresses to members in this
range for the purposes of peering across our LAN, and
LINX DOES NOT MANAGE THESE DEVICES, where DNS is not
linx.net
To report problems that relate to another ISP's network
please look them up by the peer *AS NUMBER*
on your router, or via the LINX looking glass,
or the reverse DNS, or otherwise contact
the peer ISP directly
