I’m in Italy and my ISP is Wind / Infostrada (WIND Telecomunicazioni S.p.A.), autonomous system AS1267. My current public IP is 220.127.116.11.
If I lookup the FQDN “whatismyip.akamai.com” with 18.104.22.168 I receive these IPs:
Instead if I lookup “whatismyip.akamai.com” with 22.214.171.124 (Google DNS), or with the DNS of my ISP, I always receive these IPs:
Well, it seems that 126.96.36.199 (Google DNS) is doing “a better lookup” due to geolocalization of the IP of origin (my Public IP) and so will answer always with the “best” IP in term of latency because 151.x.x.x is the same network of Wind / Infostrada (WIND Telecomunicazioni S.p.A.), autonomous system AS1267.
In fact I can ping 188.8.131.52 or 184.108.40.206 with only 5ms, instead when I ping 220.127.116.11 or 18.104.22.168 the latency is about 16ms (and in my case it is routed externally via telia.net).
Please, can you “improve” for 22.214.171.124 the DNS lookup for “whatismyip.akamai.com” so it will answer with “the best” IPs such as 126.96.36.199 and 188.8.131.52 for customers of Wind / Infostrada (WIND Telecomunicazioni S.p.A.), autonomous system AS126?
