I have to put in my table a new type of data:
IP and NETADDRES
how can I do?
what is (for you) the best way to do it?
I think I'll make 4 INTEGER ( an IP is made by 4 number eg. 121.33.122.133)
But then I have to get the little Net to which belong an IP
I mean:
if in my database there is:
121.33.122.100
121.33.00.00
121.33.00.00
and I have to know which Net belong the IP 121.33.122.143
the right choise is 121.33.122.100
so I have to order this column in right way!?!?
but how can I do than?!?!
Thank you in advance for your help.
I think to do that by ordering the column then get the first row taken by the
follow query:
select * from name_table where IP1>INT1, IP2>INT2, IP3>INT3, IP4>INT4;
where IPx is the fisrt, second,... part of an IP
and INT1, INT2... is the four columns in my db.
I hope I'm clear and I'm very sorry for my little english.
I thak very much all people had read this mail!
