Subject: Asking about the file dhcpdb.bind

 Dear Sir/Madam,
 I have read the file dhcpdb.bind but I didn't
understand much. Is that file store informations of
the one who accessed the host?
 An example of one line in that file is:
1:0x00004c438911:192.168.1.0:1:0x00004c438911:"Thu Dec
 3 19:15:11 1998":0068

 Is "1:0x00004c438911" the MAC address of the
accessing computer?
 Is "Thu Dec 3 19:15:11 1998" is the date and time of
accessing?
 And is "0068" the number of that computer which is
stored is the file dhcpdb.pool?
But which computer has the IP address "192.168.1.0"?
Because I've found that all the lines in dhcpdb.bind
have the same one ("192.168.1.0").
 Another question is what is the usage of the file
dhcpdb.bind? Now our company is very interested in the
security problem of our Internet system, could we use
that file to inquire who had accessed our system?
 Would you please help me or tell me where I could
find the answer? Now I couldn't have any detail
document about that.
 I'm very sorry if my questions is so silly because
I'm very new in both UNIX and Free BSD. I'm using Free
BSD version 3.3.
 I'm Vietnamese but now working in Japan, I've found
that many Japanese sites are concerned in Free BSD and
security fields. I can understand Japanese so if you
could have some Japanese answers or documents, you
couldn't have to translate them into English.
 Thank you very much in advanced, and looking forward
your reply,

 Tran Ngoc Thuan An
