Unit 9

Wired Networking: How You Get Connected

What Happens During the Boot Process:

1. Push power

2. POST runs

3. BIOSes get read into RAM

4. NIC BIOS gets read into RAM

5. Every NIC has a MAC address (48 bits, Hex) like:


6. The NIC sends out a frame FROM: its MAC, TO: Broadcast (BC)

Ethernet Broadcast Address is:

ffffffffffff (note that this is 48 1s)

0000 = 0

0001 = 1

1111 = f

7. The switch it’s connected to hears the BC, and registers the new MAC address to the physical port it’s plugged into.

8. If NetBEUI/NetBIOS are being used (DOS, Windows 95/98, Windows NT3.x):

a. The Local Browse Master for NetBEUI/NetBIOS hears the initial NIC BC, and

b. Registers the host’s NetBIOS name and MAC address to the local Workgroup.

9. If IPv4 is being used:

a. NIC broadcasts to the IPv4 BC address: ipv4 address is 32 bits, IN DECIMAL

The IPv4 BC address is: (note that this is 32 1s)

b. DHCP gives me






10. If IPv6 is being used:

a. The router gives you a Network Number to prefix your Host ID, forming a 128-bit IPv6 address.

b. The NM is always /64, except in very esoteric cases.

c. The router itself is the default GW.

d. All you’re missing is a couple of DNS Name Servers, and this is all that IPv6 DHCP has to do. Even this functionality will disappear (along with IPv6 DHCP) when routers incorporate this DNS information.
