Find out if an IP is within a range of IPs

Question

How can you tell if an ip, say 62.156.244.13 is within the range of 62.0.0.0 and 62.255.255.255

Answer 1

jdl's answer is good. I would make the in_range? function a one-liner:

def ip_addr_in_range?(low, high, addr)
  (numeric_ip(low) .. numeric_ip(high)) === numeric_ip(addr)
end
