Hello,
I have many computers, mobile devices and IOT devices in my home, but the two Windows 10 laptops that have ESET Smart Security (v13.2.18.0 as of this writing) continue to both receive the same notifications:
Network Event Blocked. Duplicate IP on Network. A Computer (169.254.1.1) on the network is sending malicious traffic. This can be an attempt to attack your computer.
Remote address: 169.254.1.1.
Continue Blocking / Allow
Could someone please help me troubleshoot this and get to the root of the issue? Is this an ESET issue or is there really something wrong with my network. I have other devices with different security software, yet none of them show any errors at all.
My network does not have a device with this IP address. Google search states IP address 169.254. 1.1 is likely assigned by the host itself. This occurs when a Windows machine has been configured for DHCP but for whatever reason are unable to contact the DHCP server. Microsoft term for this is Automatic Private Internet Protocal Addressing (APIPA).
ISP: Xfinity (Comcast)
Modem: Purchased my own. Netgear Nighthawk CM1150V (compatible w/ Xfinity)
Mesh Network: (1) Synology RT2600ac Mesh Wi-Fi router with (2) Synology MR2200ac additional Wi-Fi Points extending coverage.
DHCP server: enabled
IPv6: enabled and setup as DHCPv6-PD
I can provide any logs and/or information you may need. The Synology router management system is ridiculously easy to configure and it currently states my network is healthy with no issues.
Thanks in advance!
