Sapendo quali sono i servizi aperti sul computer, il malintenzionato cerca di scoprire quali di questi sono vulnerabili. My home network is a class C network with IPs 192.168.0.X. Effettua un port scan online Quando un attaccante vuole intrufolarsi dentro ad un computer parte quasi sempre da una attività molto semplice: il portscanning. Scanning a range belonging to a Class C network is easy using a hyphen to define the range. There are a lot more to say about subnetworks, but this is the basic knowledge we need for this tutorial on Nmap, for more information on this specific subject visit. So if your network is 192.168.0.X, the first 3 octets will remain and only the final octet will be different for each device, one may be 192.168.0.3, other 192.168.0.5, first 3 octets will remain as network identifiers. Therefore if your network starts as 192.X.X.X you have a Class C IP and only the final octet will vary to identify each device connected to your network. Where: X is the network address and Y the host address. All IP addresses with the first octet going from number 128 to 191 belong to class B and All IP addresses with the first octet going from number 192 to 223 belong to class C. While there are 5 classes of IP addresses (for the IPV4 protocol only) for this tutorial I’ll focus only on classes A, B and C.Īll IP addresses with the first octet going from the number 1 to 126 belongs to class A.

Brief introduction to subnetsįor this tutorial all we need to know about subnetworks is they are division between the network address and hosts addresses.
