That 00:0E:35:6F:3E:33 is a MAC of the NIC (Network Interface Card) all
cards wired or wireless has a unique MAC for a card.
Here are some examples of how to determine the NIC MAC of the computer's
NIC. You should identify all NIC MAC's that are accessing your network
http://www.cs.mu.oz.au/register/macHelp.html
The only times I have seen that message at work is when another machine
on the network was being assigned the same DHCP IP on the network my
machine was already using and was trying to access/get on the network --
the conflict.

You can check the IP that is being assigned to a NIC'S MAC in the
router's DHCP table logs. You should not be getting the conflict because
the router is going to assign IP(s) based on the NIC's MAC and the
machine should be getting the same IP based on MAC assignment. There
should be no conflict unless two computers active on the network are
conflicting for the same IP.
Now, it could be a sign that someone is trying to hack your wireless
network by being slick in trying to access your network by giving his/her
machine's NIC a static IP on your router of 192.168.1.100 even though
it's a DHCP IP to one of your machines, which there will be no log entry
for their NIC's MAC in the router's DHCP table logs when using a static
IP other than your own computer's MAC. It could be away of covering
tracks by using the same IP you are using when your machine is not on the
network using the 192.168.1.100, possibly your machine is turned off.
I don't see why someone couldn't do it. And you wouldn't know if it was
happening possibly due to the router not have a logging feature where you
could review network traffic to/from the router by LAN IP(s) to remote
Internet IP(s). You could possibly look at the traffic for 192.168.1.100
and determine that your machine that should be using 192.168.1.100 was
not on the network at that time and you don't recall accessing the remote
IP site, which you can determine who the IP belongs to by using something
like Arin Whois. But the router must have the logging feature and
possibly using a log viewer like Wallwatcher.

You want to find out about a remote IP you enter the IP into the Search
Whois box.

It's possible I would think.
