Explanation:
A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.
Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.
Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
Basically, a DHCP server is designed to automatically assign internet protocol (IP) address to network devices connected to its network using a preconfigured DHCP pool and port number 67.
On a related note, when a computer that is configured with DHCP cannot communicate or obtain an IP address from the DHCP server, the Windows operating system (OS) of the computer automatically assigns an IP address of 169.254.33.16, which typically limits the computer to only communicate within its network.

BlueBorne Attack
Explanation:
If you're using a Bluetooth enabled device, whether it's a smartphone, laptop, smart TV, or any other IoT device, you risk malware attacks that can be remotely performed to take over your device, even without requiring any interaction from your side.
Security researchers have just discovered a total of 8 zero-day Bluetooth protocol vulnerabilities affecting more than 5.3 billion devices - from Android, iOS, Windows and Linux to the Internet of devices (IoT) - using technology short-range wireless communication
Using these vulnerabilities, security researchers at IoT security firm Armis created an attack, called BlueBorne, which could allow attackers to completely take over Bluetooth-enabled devices, spread malware, or even establish a “man” connection. -in-the-middle ”to gain access to device critical data and networks without requiring any victim interaction.
