Hello, Our AS855 can't seem to contact the DNS servers for atac.fr domains (dns.atac.fr [62.160.25.65] & dns2.atac.fr [195.68.125.36]). From our network, dig dies for both IPs: ------------------------------------------------------------------------------ ;; Received 401 bytes from 192.33.4.12#53(c.root-servers.net) in 17 ms atac.fr. 172800 IN NS dns2.atac.fr. atac.fr. 172800 IN NS dns.atac.fr. ;; Received 94 bytes from 194.57.253.1#53(E.NIC.fr) in 316 ms dig: couldn't get address for 'dns2.atac.fr': not found ------------------------------------------------------------------------------ If I use dig from public web sites it works: ------------------------------------------------------------------------------ ;; Received 401 bytes from 192.203.230.10#53(e.root-servers.net) in 94 ms atac.fr. 172800 IN NS dns2.atac.fr. atac.fr. 172800 IN NS dns.atac.fr. ;; Received 94 bytes from 194.57.253.1#53(E.NIC.fr) in 313 ms atac.fr. 300 IN A 194.145.56.21 atac.fr. 300 IN NS dns.atac.fr. atac.fr. 300 IN NS dns2.atac.fr. ;; Received 110 bytes from 195.68.125.36#53(dns2.atac.fr) in 113 ms ------------------------------------------------------------------------------ A traceroutes die as well: traceroute 195.68.125.36 .... 9 ae-2-79.edge1.NewYork1.Level3.net (4.68.16.78) [AS 3356] 25.278 ms ae-1-69.edge1.NewYork1.Level3.net (4.68.16.14) [AS 3356] 25.284 ms ae-4-99.edge1.NewYork1.Level3.net (4.68.16.206) [AS 3356] 27.476 ms 10 COLT-TELECO.edge1.NewYork1.Level3.net (4.78.132.22) [AS 3356] 25.871 ms 26.014 ms 25.589 ms 11 * * * 12 90.168-14-84.ripe.coltfrance.com (84.14.168.90) [AS 8220] 114.992 ms 114.912 ms 115.243 ms 13 * * * traceroute 62.160.25.65 ... 9 ae-2-79.edge2.NewYork1.Level3.net (4.68.16.80) [AS 3356] 25.573 ms 25.429 ms ae-3-89.edge2.NewYork1.Level3.net (4.68.16.144) [AS 3356] 25.591 ms 10 francetelecom-level3-te.NewYork1.Level3.net (4.68.111.86) [AS 3356] 39.905 ms francetelecom-level3-te.NewYork1.Level3.net (4.68.111.82) [AS 3356] 33.916 ms 33.762 ms 11 * * * It appears as though packets aren't making their way back.
