ipaddrとipnetの間で比較する流れを完全に想像だけで書いてみるｗ
function conv(ip)
Dim ipary
ipary = split(ip,".")
conv = clng(ipary(0)*256^3) + clng(ipary(1)*256^2) + clng(ipary(2)*256) + clng(ipary(3))
end function
function bitmask(masklng)
Dim mask
mask = clng(0)
for i = 31 to 31-masklng
mask = mask + clng(2^i)
next
bitmask = clng(mask)
end function
function check(ipaddr,ipnet)
ary = split(ipnet,"/")
netaddr = conv(ary(0))
mask = bitmask(ary(1))
if (clng(netaddr) = clng(conv(ipaddr)) and clng(mask)) then
check = true
else
check = false
end if
end function
clngの挟み方は適当。多分使いすぎ。
bitmask辺りは99%の確率でバグってる悪寒ｗ
