Hello, While experimenting IPv6 and NAT-PT implementations using the "totd" as a DNS proxy, I found a small bug !?. Aparently it can't deal with more than 2 levels of alias in a DNS response and it hang's the aplication that make the dns query (ex. Browser, ping, traceroute) returning a no address message. My question is, is it suposed to do that or is it a detail to be corrected in totd ? Thank you for your attention, Fernando Correia CICA-FEUP Portugal natpt# host www.microsoft.com www.microsoft.com is a nickname for www.microsoft.akadns.net www.microsoft.akadns.net is a nickname for www.microsoft.com.edgesuite.net www.microsoft.com.edgesuite.net is a nickname for a562.cd.akamai.net a562.cd.akamai.net has address 63.208.194.103 a562.cd.akamai.net has address 63.208.194.30 a562.cd.akamai.net has address 63.208.194.32 a562.cd.akamai.net has address 63.208.194.33 a562.cd.akamai.net has address 63.208.194.54 a562.cd.akamai.net has address 63.208.194.65 a562.cd.akamai.net has address 63.208.194.89 a562.cd.akamai.net has address 63.208.194.94 a562.cd.akamai.net has address 63.208.194.96 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c220 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c221 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c236 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c241 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c259 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c25e a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c260 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c267 a562.cd.akamai.net has address 2001:690:2200:9a0f::3fd0:c21e natpt# ping6 www.microsoft.com ^C natpt# traceroute6 www.microsoft.com ^C natpt# traceroute6 www.microsoft.com.edgesuite.net traceroute6 to a562.cd.akamai.net (2001:690:2200:9a0f::3fd0:c23f) from 2001:690:2200:9a00::1, 30 hops max, 12 byte packets 1 2001:690:2200:9a00::1 0.255 ms 0.287 ms 0.206 ms 2 gw-e26-51 0.818 ms 0.797 ms 0.659 ms 3 nokia 3.698 ms 0.97 ms 1.896 ms 4 2001:690:2200:9a0f::c189:37c1 7.616 ms 2.006 ms 2.472 ms 5 Router15.ATM1-0-3.Porto.fccn.pt 3.444 ms 5.759 ms 5.198 ms 6 ROUTER11.GE.Porto.fccn.pt 9.431 ms 7.741 ms 8.116 ms 7 ROUTER8.GE.Lambda.Lisboa.fccn.pt 9.984 ms 12.139 ms 12.165 ms 8 ROUTER1.GE0-2-0.5.Lisboa.fccn.pt 12.517 ms 11.321 ms 9.506 ms 9 rccn.es1.es.geant.net 22.307 ms 20.046 ms 19.294 ms 10 es.it1.it.geant.net 42.292 ms 44.112 ms 48.737 ms 11 so-0-1-0.ar2.LIN1.gblx.net 52.529 ms 45.138 ms 48.873 ms 12 pos6-0-2488M.cr1.LIN1.gblx.net 44.207 ms 48.044 ms 43.995 ms 13 pos0-0-2488M.cr1.LON3.gblx.net 70.024 ms 70.034 ms 73.83 ms 14 so6-0-0-2488M.ar2.LON3.gblx.net 74.315 ms 73.231 ms 69.67 ms 15 Level-3public-peering.ge-5-0-0.ar2.LON3.gblx.net 67.553 ms 79.326 ms 74.5 ms 16 ae-0-54.mp2.London1.Level3.net 74.911 ms 69.735 ms 67.265 ms 17 so-1-0-0.bbr2.NewYork1.Level3.net 134.753 ms 144.419 ms 135.479 ms 18 unknown.Level3.net 138.965 ms 146.14 ms 144.14 ms 19 ge-11-0.hsa1.Boston1.Level3.net 140.548 ms 149.1 ms 155.919 ms 20 unknown.Level3.net 148.376 ms 151.731 ms 148.32 ms natpt#
