@viktik ...I am not sure about this,but personally I would block it to be on the safe side...
It does come from..
Internet Assigned Numbers Authority (IANA)

Coordinates 33.9829, -118.405 (Type into Google Maps)
Computers use addresses starting with "169.254." when they do not have a manually configured address or when they are not told which address to use by a service on the network. They are commonly called the "link local" addresses.
Routers are not allowed to forward packets sent from an IPv4 "link local" address, so they are always used by a directly connected device.
These addresses were assigned by the IETF, the organization that develops Internet protocols, in the Standards Track document.
I can't find anything that would make me 100% happy with this IP so I would block it.
Were you doing anything at the time that may lead you to believe that this is a legitimate remote connection attempt?....
