Each entry is phrased as the falsehood. Some of these may sometimes be true and sometimes be false. NAT My LAN is behind a NAT. I’m only behind one NAT. My LAN isn’t behind a NAT. My IPv6 hosts aren’t behind a NAT. If I have a RFC 1918 address, I’m behind a NAT. If I don’t have a RFC 1918 address, I’m not behind a NAT. NAT only translates addresses. NAT only translates addresses and ports. NAT changes nothing outside of the header. NAT is only found on LANs. Protocols Only IPv4 is running on my LAN. Only IP is running on my LAN. Okay, only IP, IPX/SPX, Phase IV, AppleTalk, VINES, NetBEUI, or SNA are running on my LAN. Seriously? I can stop certain types of traffic from using my LAN. I know what’s running on my LAN. MAC addresses MAC addresses are globally unique. (They’re supposed to be, but they aren’t.) MAC addresses are locally unique. Different MACs are different devices. Okay, different MACs are different network interfaces. MAC addresses can’t be changed. MAC addresses can be changed. MAC addresses are 48 bits. The first three bytes are vendor‐unique. The first three bytes are vendor‐unique if it’s a MA-L block. MAC addresses are unicast. Only one host answers an ARP request for a given IP. ARP entries are accurate. Reachability and performance The LAN is fast. The LAN is faster than the Internet. Two hosts on the same subnet can reach each other without leaving the LAN. Same subnet means two hosts can talk. Wi-Fi and Ethernet clients are equivalent peers on the LAN. Wi-Fi and Ethernet clients aren’t equivalent peers on the LAN. Every device on my LAN has the same MTU. Hostnames are locally unique. mDNS works. DHCP There is a DHCP server. There is one DHCP server. My address won’t change while I’m using it. The DHCP server and the gateway are the same device. DHCP will give me a gateway. DHCP will give me a DNS server. 169.254.0.0/16 means DHCP failed. IP addresses Every host has one IP address. My LAN uses RFC 1918 IP addresses. My LAN uses private IP addresses. My LAN uses IP addresses.
