The following packets are showing up in my IDS logs, but although the source address is part of our IP address range 
(62.254.170.9), it is not currently in use (and never has been in the past). Is someone using my IP address as a source 
address for spoofed packets? (IE, some sort of port scan) It's the only explanation I can think of.

The destination address (194.102.106.199) is listed under RIPE as a Roumanian Mobile telephone provider.

IDS is snort 1.7
