They aren't looking for an exact number but the rational for coming up with that number

Every site needs to have an ip addr. Knowing that IPv4 is running out, and take out about 3/4 of reserved IP such as 128.x.x.x - 255.x.x.x etc. assuming rest of the addr corresponded to a website. I say there are 255*255*255*255 / 4 =2^32/4 = 4.2billion /4 = 1.05billion site
