: 203.69.112.3,when I use trumpdig to resolve my IP to my DNS server,
: it's OK.
: Questions
: 3.112.69.203.IN-ADDR.ARPA PTR 1
:
:
: And then I setup the DNS server item in the program to the
: HINET DNS server(168.95.1.1 ),and it's OK,too.But when I setup my
: DNS server item to NCTU CSIE's DNS(140.113.1.1),it resolve to another
: place
: uestions
: 3.112.69.203.IN-ADDR.ARPA PTR 1
: Authorities
: 203.in-addr.arpa SOA 1 345600 jatz.aarnet.edu.au
: autodns.telstra.net
: ; size = 132
:
: So the question maybe between HINET's DNS and CSIE's DNS.
: As an end user like me,how can I do to improve my situation?
