Description:
When I use the following strings as value for inet-type fields, I get the
error "ERROR: invalid input syntax for type inet" for the first three
insert statements.
create table e (id serial primary key, ip_addr inet not null);
insert into e(ip_addr) values ('127.1'); -- short syntax for 127.0.0.1
insert into e(ip_addr) values ('3232281089'); -- integer version of
192.168.178.1
insert into e(ip_addr) values ('0xc0a8b201'); -- hex version of
192.168.178.1
insert into e(ip_addr) values ('192.168.178.1'); -- this one does work
The alternate syntax does work in Safari, and on command line utilities like
ping.
And if memory serves well, it worked in InternetExplorer 5.5 on Windows 2000
back in 2002.
Anyways, the documentation about the inet-type could say it only accepts
normalized forms of addresses.
The wikipedia has some info on this:
