What's the default value of “inet” and “cidr” type in PostgreSQL?

When I execute the SQL:
CREATE TABLE IF NOT EXISTS "xxx" (
"id" serial NOT NULL PRIMARY KEY,
"ip" inet NOT NULL DEFAULT '',
"mac_address" macaddr NOT NULL DEFAULT '',
"status" varchar(64) NOT NULL DEFAULT ''
);
It reports an error:
execute error: pq: invalid input syntax for type macaddr: ""
So what's the default value of "inet" and "cidr" type in PostgreSQL?
sql postgresql ip mac-address

Only you know what's the default value supposed to be, there's no default DEFAULT

I would be inclined to go with NULL values, instead of some default.
But, you can put in your own values if you follow the specified formats:
CREATE TABLE IF NOT EXISTS "xxx" (
"id" serial NOT NULL PRIMARY KEY,
"ip" inet NOT NULL DEFAULT '0.0.0.0'::inet,
"mac_address" macaddr NOT NULL DEFAULT '00-00-00-00-00-000'::macaddr,
"status" varchar(64) NOT NULL DEFAULT ''
);
