c# ip address generator to SQL

I have the following python code I found on the internet, I would like to make 开发者_开发百科a table in a SQL database with every ipv4 address that there is. I dont code in python but its what I found.

My question is 1: Is there T-SQL code I can use to generate the table ? (one column ie 0.0.0.0-255.255.255.255)

2: Is how would I make this in c#? using the fastest method possible ? I know showing the results slows the console application down by 400 %

#!/usr/bin/env python
def generate_every_ip_address():
    for octet_1 in range( 256 ):
    for octet_2 in range( 256 ):
    for octet_3 in range( 256 ):
    for octet_4 in range( 256 ):
        yield "%d.%d.%d.%d" % (octet_1, octet_2, octet_3, octet_4)

for ip_address in generate_every_ip_address():
    print ip_address


Would this work?

DECLARE @a INTEGER
DECLARE @b INTEGER
DECLARE @c INTEGER
DECLARE @d INTEGER
DECLARE @IPADDRESS nvarchar(50)

set @a = 0

WHILE @a < 256
BEGIN
    SET @b = 0
    WHILE @b < 256
    BEGIN
        SET @c = 0
        WHILE @c < 256
        BEGIN
            SET @d = 0
            WHILE @d < 256
            BEGIN
                SET @IPADDRESS = CAST(@a AS nvarchar(3)) + '.' + CAST(@b AS nvarchar(3)) + '.' + CAST(@c AS nvarchar(3)) + '.' + CAST(@d AS nvarchar(3))
                PRINT @IPADDRESS
                SET @d = @d + 1
            END
            SET @c = @c + 1
        END
        SET @b = @b + 1
    END
    SET @a = @a + 1
END


To insert in batches of 16,581,375 rows would be quite straightforward using the following TSQL.

DECLARE @Counter INT
SET @Counter = 0
SET NOCOUNT ON ;

WHILE ( @Counter <= 255 ) 
    BEGIN
        RAISERROR('Procesing %d' ,0,1,@Counter) WITH NOWAIT ;

        WITH    Numbers ( N )
                  AS ( SELECT   CAST(number AS VARCHAR(3))
                       FROM     master.dbo.spt_values
                       WHERE    type = 'P'
                                AND number BETWEEN 0 AND 255
                     )
            INSERT  INTO YourTable
                    ( IPAddress
                    )
                    SELECT  @Counter + '.' + N1.N + '.' + N2.N + '.' + N3.N
                    FROM    Numbers N1 ,
                            Numbers N2 ,
                            Numbers N3 


        SET @Counter = @Counter + 1
    END


Please just use an int IDENTITY column to store each IP address. They're only 32 bits. Fill your table up with whatever else you're storing.
