- A VPN creates a private tunnel over public networks.
- Several tunneling protocols include PPTP, L2TP, and SSTP.
Ethernet and Port Specifications
- Ethernet operates on Layer 1 of the OSI model.
- Cat5 supports speeds of 100 Mbps, while Cat5e supports 1 Gbps.
- Unsecured websites typically use port 80, while secured ones use port 443.
Classful Addressing
- Class A example IP: 100.100.1.1; Class B example IP: 170.100.1.5; Class C example IP: 198.126.1.55; Class D example IP: 244.0.0.2.
DNS and IP Configuration Commands
- AAAA records map hostnames to IPv6 addresses.
- Commands related to IP address management include:
- ipconfig /release to delete an IP address.
- ipconfig /renew to acquire an IP address from DHCP.
- ipconfig /displaydns to show DNS cache.
- ipconfig /flushdns to purged DNS cache.
Tracing and Network Statistics
- tracert is used to trace the path of IP packets across a network.
- Use pathping to find packet loss statistics.
- netstat -a displays all listening and established ports, while netstat -p tcp shows info for TCP connections.
Routing Protocols
- RIP routing uses hop counts for route calculation, with a maximum of 15 hops.
