Vlookup for IP

I seem to have VLOOKUP on IP.  It looks up a total wrong IP. I can not figure out why.  I have sheet1 that have the I.P. address in column B that I try to lookup. In sheet2, it has list of IP that I try to lookup and put result of the VLOOKUP into column A of sheet1.  But as you can see the result is not quite right.
Can anyone help?  I attached  the file.

Add ", FALSE" at the end of your VLOOKUP like this:

=IFERROR(VLOOKUP($B2,Sheet2!$A$1:$A$161, 1,FALSE),"")
