Telescope traces

IPv4 Address Space Maps




• For analysing the source IP addresses that send packets to the telescope network over the time we visualize the following figures. Each figure represents the mapping of the sources IP addresses received during a day (with reference to the UTC).
  
  Observing the current traffic (January 2010), we notice that the source IP addresses arriving every day to the telescope belong mostly to the address space allocated through the Regional Internet Registries: RIPE, APNIC, ARIN, LACNIC, and AfriNIC. The figure also shows some addresses in the areas labeled "Various Registries" indicating the allocations to "class B" and "class C" before the mid-1990s.
  Addresses in the areas labeled as "Unallocated", "Multicast", "Future use" and in the "class A" address blocks appearing in the upper left of the maps are rare.
  
  The figures are obtained using the IPv4-heatmap software, and the labels of the blocks are based on IANA's list of IPv4 allocations.
  
  Each pixel in the images represents a single /24 network and to each one it is assigned a color. The pixel color represents the number of hosts within the /24 that sends at least one packet to the network telescope during the selected day. Pixel colors range from black (0 host) to red (256 hosts), as shown in the colorbar.
