The basis are IPv4 traceroutes from all (4500+) RIPE Atlas probes to the anchor encoded in the file name. The graphs show adjacencies that appear in more than 3% of all paths. IP addresses are aggregated by the network name as registered in the RIR registries. The darker an edge appears, tho more paths contain this adjacency; the colouring is scaled logarithmically.</div><div><br></div><div>Enjoy</div><div><br></div><div>Daniel</div><span class="Apple-tab-span" style="white-space:pre"> </span><img height="600" width="600" apple-width="yes" apple-height="yes" id="26f8a4b3-5431-4927-8785-4cada179cb71" src="cid:0D411895-DEA3-4FAD-BAF6-AFA0F47F85ED@karrenberg.net"><img height="1067" width="1067" apple-width="yes" apple-height="yes" id="23976334-66e1-4d7d-9acd-43e06a96f9a2" src="cid:FF09536F-3B29-465F-A2B3-3139F623CD2C@karrenberg.net"><img height="1067" width="1067" apple-width="yes" apple-height="yes" id="ad8e3385-1fac-4941-b131-b0616c0cf674" src="cid:5B5A3A2D-AFB2-4459-874B-ECC2F681EDDD@karrenberg.net"><img height="1067" width="1067" apple-width="yes" apple-height="yes" id="2fca22ec-30be-4de1-81a5-c6388d1a9064" src="cid:6EA9860B-273E-4AE7-9468-E17151591FBD@karrenberg.net"><img height="1067" width="1067" apple-width="yes" apple-height="yes" id="055dbb07-6c48-4497-b3a4-d62fbf6bedb9" src="cid:2F5106DD-FAF4-4DF6-85EA-36EDEDC25D68@karrenberg.net"></body></html>
