Question

When I try to insert the below into my MySQL

INSERT INTO `rooms` (`id`, `ip`) VALUES ('131213', '-259857341');

I fails with the follow error:

Warning: #1264 Out of range value for column 'ip' at row 1

I am looking around but haven’t found how to fix or work it out…

My field is unsigned int which should work just fine for that entry.

What is the problem and how do I solve ?

I am using unsigned int because I wanted to store ips using inet_ntoa/aton.

EDIT:

I am using unsigned INT as recommend in MySQL website:

To store values generated by
INET_ATON(), use an INT UNSIGNED
column rather than INT, which is
signed. If you use a signed column,
values corresponding to IP addresses
for which the first octet is greater
than 127 cannot be stored correctly.
See Section 10.6, “Out-of-Range and
Overflow Handling”.

Unsigned integer means non-negative value at least.

Not sure if this is what you need but you can try to convert signed integer to 4 bytes unsigned integer as your ipconverter does (http://www.silisoftware.com/tools/ipconverter.php):

INSERT INTO `rooms` (`id`, `ip`) VALUES ('131213', '-259857341' & 0xffffffff);
