The IP address belongs to the class A. What is the network address then? 3. How is the broadcast address calculated from the IP address and from the subnet mask? 4. Translate \"10.50.1.131/25\" to \"10.50.1.131 netmask x.x.x.x\" notation. 5. Is OSPF always loop free? 6. HUT has IP address space of B class. What is the network address of HUT? 7. Hubs haven't IP addresses, why? 8. How is the IP address of class C recognized? 9. What is the netmask of class C? 10. ARP works on the link layer, not on IP? Why?
