Summarize 2001:DB8:0:A480::/64 to
Note that 0x80=128, 0xBF=191.
Give an example of role-based addressing
using network 10.
10.1.10/24 – Closet 1, VLAN 10
10.1.20/24 – closet 1, VLAN 20
etc. (No bit splitting here)
You need to deploy role-based addressing
using only the class B private address space 172.16/12. Assume that you have 50 closets in campus, and each closet needs to accommodate 250 users. How many VLANs can you allocate to each closet?
- You need 6 bits for closets (2^6=64), 8
- bits for users (2^8=256), so you get 6 bits -> 64 for VLANs.
