dnstracer determines where a given Domain Name Server (DNS) gets its information from, and follows the chain of DNS servers back to the servers which know the data.
Example :-
[~] edwin@k7>dnstracer www.mavetju.org Tracing to www.mavetju.org via 127.0.0.1, timeout 15 seconds 127.0.0.1 (127.0.0.1) |\___ B.ROOT-SERVERS.NET [.] (128.9.0.107) | |\___ M.GTLD-SERVERS.NET [org] (202.153.114.101) | | |\___ NS2.SECONDARY.COM [mavetju.org] (198.133.199.4) Got authoritative answer | | \___ NS1.SECONDARY.COM [mavetju.org] (198.133.199.3) Got authoritative answer | |\___ E.GTLD-SERVERS.NET [org] (192.12.94.30) | | |\___ NS2.SECONDARY.COM [mavetju.org] (198.133.199.4) (cached) | | \___ NS1.SECONDARY.COM [mavetju.org] (198.133.199.3) (cached) | |\___ K.GTLD-SERVERS.NET [org] (213.177.194.5) | | |\___ NS2.SECONDARY.COM [mavetju.org] (198.133.199.4) (cached) | | \___ NS1.SECONDARY.COM [mavetju.org] (198.133.199.3) (cached) [...] | \___ A.GTLD-SERVERS.NET [org] (192.5.6.30) | |\___ NS2.SECONDARY.COM [mavetju.org] (198.133.199.4) (cached) | \___ NS1.SECONDARY.COM [mavetju.org] (198.133.199.3) (cached) |\___ F.ROOT-SERVERS.NET [.] (192.5.5.241) | |\___ M.GTLD-SERVERS.NET [org] (202.153.114.101) (cached) | |\___ E.GTLD-SERVERS.NET [org] (192.12.94.30) (cached) | |\___ K.GTLD-SERVERS.NET [org] (213.177.194.5) (cached) | |\___ J.GTLD-SERVERS.NET [org] (210.132.100.101) (cached) | |\___ F.GTLD-SERVERS.NET [org] (192.35.51.30) (cached) [...] | \___ A.GTLD-SERVERS.NET [org] (192.5.6.30) (cached) |\___ G.ROOT-SERVERS.NET [.] (192.112.36.4) | |\___ M.GTLD-SERVERS.NET [org] (202.153.114.101) (cached) [...]
