Its pretty easy to do this using a macro..If you are looking for a formula
try the below (bit lengthy)

In Result sheet cell A1 enter the IP number

In cell B1 enter the below formula. Please note that this is an array
formula. You create array formulas in the same way that you create other
formulas, except you press CTRL+SHIFT+ENTER to enter the formula. If
successful in 'Formula Bar' you can notice the curly braces at both ends like
"{=<formula}"

The result for the sample you pasted would be as below (which is different
from what you have posted)

192.170.30.30 AG
194.168.10.20 AG
10.131.37.20 AP
10.170.255.255 #N/A
10.129.36.8 AP



=INDEX('IP Range'!$C$1:$C$10,
MATCH(1,(TEXT(LEFT(SUBSTITUTE('IP Range'!$A$1:$A$10,"."," "),3),"000")&
TEXT(MID(SUBSTITUTE('IP Range'!$A$1:$A$10,"."," "),7,6),"000")&
TEXT(MID(SUBSTITUTE('IP Range'!$A$1:$A$10,"."," "),13,9),"000")&
TEXT(RIGHT(SUBSTITUTE('IP Range'!$A$1:$A$10,"."," "),3),"000")<=
TEXT(LEFT(SUBSTITUTE(A1,"."," "),3),"000")&
TEXT(MID(SUBSTITUTE(A1,"."," "),7,6),"000")&
TEXT(MID(SUBSTITUTE(A1,"."," "),13,9),"000")&
TEXT(RIGHT(SUBSTITUTE(A1,"."," "),3),"000"))*(
TEXT(LEFT(SUBSTITUTE('IP Range'!$B$1:$B$10,"."," "),3),"000")&
TEXT(MID(SUBSTITUTE('IP Range'!$B$1:$B$10,"."," "),7,6),"000")&
TEXT(MID(SUBSTITUTE('IP Range'!$B$1:$B$10,"."," "),13,9),"000")&
TEXT(RIGHT(SUBSTITUTE('IP Range'!$B$1:$B$10,"."," "),3),"000")=
TEXT(LEFT(SUBSTITUTE(A1,"."," "),3),"000")&
TEXT(MID(SUBSTITUTE(A1,"."," "),7,6),"000")&
TEXT(MID(SUBSTITUTE(A1,"."," "),13,9),"000")&
TEXT(RIGHT(SUBSTITUTE(A1,"."," "),3),"000")),0))
