Resending this. Aplogies for duplicates if any.
maybe I am not understanding it right. Here is my problem.
I have a table like this
Attribute | Type | Modifier
--------------+--------------------------+----------
ip | cidr | not null
with following rows
ip
---------------
10.0.0.1/32
10.0.0.50/32
10.0.0.255/32
11.0.0.0/32
11.0.1.200/32
11.0.1.20/32
(6 rows)
should not the command
DELETE from ip_space where ip = '11.0.1.0/24'::cidr
delete last two rows ? But it does not delete anything. Basically I would
like to be able to delete a whole range or block of ip/network addresses.
I suppose I could rewrite the above sql as
delete from ip_space where ip >='11.0.1.0/24'::cidr and ip
<='11.0.2.0/24'::cidr;
Then it works. But I should not have to do that. Right ?
Thanks in advance. Please email and post here.
