You may try and play with the following batch files.  They work fine for me but you may have to play with them to make them work with anything less than 100.  

Name this pingall.bat replace with the first 3 octs of your domain. This also assumes that you will get "Reply" for a good reply

@echo off
:START
call add.bat
ping 127.0.0.%H%%T%%D% | find "Reply" > nul
if not errorlevel 1 echo %H%%T%%D% >> GoodPing.txt
if %H%%T%%D%==254 goto DONE
goto START
:DONE


Call this add.bat and put in the same directory.

:: ADD.BAT
:: Increments a three digit number
:: Works by comparing each digit
:: H=hundreds, T=tens, D=digits
@echo off
if [%H%]==[] set H=1
if [%T%]==[] set T=0
if [%D%]==[] set D=0
:DIGITS
if %D%==9 goto TENS
if %D%==8 set D=9
if %D%==7 set D=8
if %D%==6 set D=7
if %D%==5 set D=6
if %D%==4 set D=5
if %D%==3 set D=4
if %D%==2 set D=3
if %D%==1 set D=2
if %D%==0 set D=1
goto DONE
:TENS
set D=0
if %T%==9 goto HUNDREDS
if %T%==8 set T=9
if %T%==7 set T=8
if %T%==6 set T=7
if %T%==5 set T=6
if %T%==4 set T=5
if %T%==3 set T=4
if %T%==2 set T=3
if %T%==1 set T=2
if %T%==0 set T=1
goto DONE
:HUNDREDS
set T=0
if %H%==9 set H=0
if %H%==8 set H=9
if %H%==7 set H=8
if %H%==6 set H=7
if %H%==5 set H=6
if %H%==4 set H=5
if %H%==3 set H=4
if %H%==2 set H=3
if %H%==1 set H=2
if %H%==0 set H=1
goto DONE
:DONE
echo %H%%T%%D%


You may strip the HUNDREDS off for the first 89 and then use the full format for all over 100.  Play with it and see what you think.

It looks the proposed answer cannot do ping from 150.66.87.10 to 150.66.87.200 as the asker mentioned.

How about FOR /L %A IN (10,1,200) DO PING 150.66.87.%A

Do a HELP FOR in a command box to get the FOR syntax..

BlackMan's comment should be the answer. Hmm, it looks such command only can be done on NT system.

That's right, Extended For is only on NT, but then, this is NT Networking :-)

BlackMan, do you notice that NT's help does not include any information on Extended For. Does original version of NT4 support it? Maybe only with SP3, I think.

I've used it since the initial build of NT 4, even NT 3.51 has some of the functions..
