Study Notes
Configuring IP Addresses
- IP address configuration can be manual (static) or dynamic (via DHCP).
- Static addressing is suitable for small networks, while DHCP is effective for larger networks.
- DHCP assigns not only IP addresses but also subnet masks, default gateways, and DNS server addresses.
NIC Configuration and Verification
- Configuration of a Network Interface Card (NIC) to use DHCP can be executed on Windows.
- Use the command
ipconfig /allto verify network settings and usepingfor testing connectivity.
Wireless Network Configuration
- Configuring a wireless network involves setting up a router to manage basic settings, NAT, firewall, and Quality of Service (QoS).
- Labs demonstrate configuring wireless networks and firewall settings, focusing on MAC filtering, DMZ, and port forwarding.
Internet of Things (IoT)
- The internet is expanding to include IoT devices, such as automobiles, biomedical devices, and smart household appliances.
- IoT configuration often varies by device; manufacturer documentation is essential.
- Packet Tracer is used for exploring IoT device configurations.
Networking Skills for Technicians
- Understanding network components includes NICs, switches, access points, and routers.
- Network design knowledge is crucial, as small and large businesses have different networking needs.
- A small business may benefit from a home or small office wireless router with multiple functionalities.
Firewall and Network Security
- MAC address filtering is a basic security option; more robust solutions include port security and separate firewalls.
- Whitelisting and blacklisting control access to specific IP addresses through access lists on wireless routers.
Evolution of the Internet
- Today's internet includes not just computers, but diverse IoT devices like smart thermostats and security systems.
- The IoT market lacks standardized installation and configuration protocols, leading to device-specific settings.
Troubleshooting Network Issues
- Familiarity with troubleshooting processes is key for IT professionals; understanding MAC and IP address architecture is fundamental.
- Troubleshooting includes configuring both wired and wireless networks, firewalls, and IoT devices.
Understanding Network Addresses
- Devices in a network have two unique identifiers: the hard-coded MAC address and the changeable IP address.
- MAC addresses identify the device on a network like a fingerprint, while IP addresses function like mailing addresses that can vary.
