Network Configuration
Classroom 344 (Cisco Lab / Netlab)
Workstations
IPv4 address assignment is performed by the classroom DHCP server based on the computer’s MAC address.
Important:
Do not change the connection between network cables and network adapters, otherwise network booting will no longer work.
| Computer Location | IPv4 Address Suffix |
|---|---|
| Instructor workstation | 100 |
| Student workstations (according to MAC registry order) | 101 102 … 124 |
| IPv4 network | 10.3.44 |
| IPv4 netmask | 255.255.255.0 |
| IPv4 pool | 10.3.44.192/18 |
