  1. 1. Cyber Ethics – Scanning By Noah Franklin J
  2. 2. Session Flow• IP Addresses.• Types of IP Addresses.• Class Ranges.• IP Addresses Versions.• NAT – Network Address Translation Copy Rights to Noah Franklin J
  3. 3. IP Addresses• Every Computer that is connected to internet hasunique IP Address.• It is 32 bit number.• Two types of IP Address.• Static IP – Remain Same at every session• Dynamic IP – Changed at Every Session. Copy Rights to Noah Franklin J
  4. 4. IPV4IPv4Internet Protocol version 4 (IPv4) is the fourth revisionin the development of the Internet Protocol (IP) and itis the first version of the protocol to be widelydeployed.IPv4 uses 32-bit (four-byte) addresses, which limitsthe address space to 4,294,967,296 (232) possibleunique addresses. Copy Rights to Noah Franklin J
  5. 5. IPV6IPv6IPv6 has a much larger address space than IPv4. Thisis based on the definition of a 128-bit address,Whereas IPv4 used only 32 bits. The new addressspace thus supports 2128 (about 3.4×1038)addresses. Copy Rights to Noah Franklin J
  6. 6. IP Address Classes Copy Rights to Noah Franklin J
  7. 7. IPConfig• Ipconfig is a DOS utility which can be used from MS DOS and aMS-DOS shell to display the network settings currently assigned andgiven by a network. This command can be utilized to verify a networkconnection as well as to verify your network settings. Copy Rights to Noah Franklin J
  8. 8. NATNetwork address translation (NAT) is the process of modifyingnetwork address information in datagram packet headers while intransit across a traffic routing device for the purpose of remapping agiven address space into another. Copy Rights to Noah Franklin J
