Hi, all. I am a computer networks PhD student analyzing RIPE anchoring measurements for research purposes. While I was looking at traceroutes originating from specific anchors, I noticed that all traceroutes from Anchor #7106 only contained one hop, with no silent hops present. Upon further inspection, these singleton hops were actually the destination IP addresses themselves, and they had extremely short (<1ms) RTTs from 7106 even when they were supposed to be located on the other side of the globe. On the other hand, ping and traceroute measurements directed *toward* 7106 all seemed normal, with regular hop counts and RTTs that seemed to agree with reported geographical distance. I strongly suspect that 7106 is connected to a local proxy that is responding to outgoing ping and traceroute traffic on behalf of its intended destinations. As such, I wanted to bring some attention to this anchor so that other researchers might be aware of its status before trying to use it to conduct measurements. Regards, William Kanieski
