Study Notes
- Here are some study notes based on your provided content
Sniffing Attack
- Captures network traffic secretly
DDoS vs DoS
- DDoS attacks come from multiple devices, differentiating them from DoS attacks
Poisoning Attack
- Redirects data to a wrong place
Data Delivery Protocol
- TCP is the protocol that ensures data is delivered correctly
TCP Three-Way Handshake
- The last step in the TCP three-way handshake is ACK
UDP vs TCP Speed
- UDP is considered faster than TCP because it skips delivery checks

ARP Protocol
- ARP protocol maps IP to MAC addresses
IPv6 Address Bits
- An IPv6 address uses 128 bits
DNS A Record
- An A record in DNS links a domain to an IPv4 address
DNS IPv6 Link
- AAAA is the DNS record type that links to an IPv6 address
Reverse DNS Lookup
- PTR record is used for reverse DNS lookups
