The problem of converting numeric type to decimal IP has already been solved here:
http://cn-dos.net/forum/viewthread.php?tid=45528&fpage=1

But the other way around, how do you convert decimal IP to numeric IP?

I don't know whether CMD has any simple way for the numeric range.

Below is a VBS one:
IP = "223.255.255.255"
dip = Split(IP,".")
outip = dip(0) * 256 * 256 * 256
outip = outip + dip(1) * 256 * 256
outip = outip + dip(2) * 256
outip = outip + dip(3)
MsgBox outip

Thanks, brother slore. This only converts a single IP; it's my fault for not making it clear.
It's like this: through "ShowIp.exe" (a tool for the Chunzhen IP database) I get the text file ip.txt, with content in the following format:
0.0.0.0 0.255.255.255 IANA CZ88.NET
1.0.0.0 1.51.255.255 IANA CZ88.NET
1.52.0.0 1.52.255.255 United States CZ88.NET
1.53.0.0 1.153.255.255 IANA CZ88.NET
1.154.0.0 1.154.255.255 United States CZ88.NET
1.155.0.0 1.255.255.255 IANA CZ88.NET
2.0.0.0 2.255.255.255 IANA CZ88.NET
3.0.0.0 3.255.255.255 United States General Electric Company, New Jersey
4.0.0.0 4.9.255.255 United States CZ88.NET
4.10.0.0 4.10.255.255 United States New Jersey State University
......

How can I get file ip_out.txt with content in the format:
0 16777215 IANA CZ88.NET
16777216 33554431 IANA CZ88.NET
33554432 50331647 United States CZ88.NET
........

Bumping this myself
Waiting for an expert to solve it....

Sure enough, after 128 it gets very troublesome～

Improved the formatting, and simplified the code

@echo off&setlocal enabledelayedexpansion
for /f "tokens=1-8,* delims= . " %%a in ('type ip.txt') do (
Call :GetDIP %%a %%b %%c %%d one
Call :GetDIP %%e %%f %%g %%h tow
if "!one:~4,1!"=="" set/p "= "<nul
echo !one! !tow! %%i
)
pause
goto :eof

:GetDIP
set /a sur=%2*256*256+%3*256+%4

if %1 gtr 127 (
set /a "sur=(%1-128)*256*256*256+!sur!"
set suw=000000000!sur:~-9!
set /a suw=1!suw:~-9!-1000000000+147483648
set /a sut=!sur:~0,-9!+!suw:~0,-9!+2
set "sur=!sut!!suw:~-9!"
) else (
set /a sur=%1*256*256*256+!sur!
)

set "%5=!sur!"
goto :eof
