The answer would be after the QUESTION section. The server it asked (192.168.1.1) didn't have any data to give back to the query. > --------------------------------------------------------------------------------------------------------------------- > dig -x 192.168.1.69 > ;; Warning: Message parser reports malformed message packet.

And if DNS is fully working, doing a dig against the name, should come back with the same IP. Is that a domain that you own, or has the query gone through to your ISP? (If 192.168.1.1 didn't know the answer, it can ask further up the chain.) If I do a "dig telecomitalia.it" I get a public IP. If you're shoehorning your LAN into your ISP's domain name, or anybody else's domain name, you're likely to strike problems. > ------------------------------------------------------------------------------------------------------- > digging from laptop to pcdesktop1: > > [antonio@Fujiantonio ~]$ dig -x 192.168.1.3 > > ; <<>> DiG 9.10.2-P4-RedHat-9.10.2-5.P4.fc22 <<>> -x 192.168.1.3 > ;; global options: +cmd > ;; Got answer: > ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 7666 > ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 > > ;; OPT PSEUDOSECTION: > ; EDNS: version: 0, flags:; udp: 4096 > ;; QUESTION SECTION: > ;3.1.168.192.in-addr.arpa.

It won't really matter where you do the query from (the same PC as the server, or over your LAN). What's 192.168.1.1? A computer or a router? -- tim@localhost ~]$ uname -rsvp Linux 3.19.8-100.fc20.i686 #1 SMP Tue May 12 17:42:35 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists. George Orwell's '1984' was supposed to be a warning against tyranny, not a set of instructions for supposedly democratic governments. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
