# Validates the range between two ip addrresses?

Hi All,

I have to input two ip addresses from apex page. i.e., ipFrom and ipTo

for example:

ipFrom - 10.35.34.90

ipTo - 10.35.34.80

Above is incorrect range.

Is there any method to validate the ip address range as above ?

Thanks.

Assuming all IPs are formatted as 4-octet numbers, you can do this:

```integer iptoint(string ip) {
string[] octet = ip.split('\\.');
return integer.valueof(octet[0])*16777216+integer.valueof(octet[1])*65536+integer.valueof(octet[2])*256+integer.valueof(octet[3]);
}

boolean isiniprange(string fromip, string toip, string currentip) {
integer lowip, highip, myip;
lowip = iptoint(fromip);
highip = iptoint(toip);
myip = iptoint(currentip);
return lowip <= myip && highip >= myip;```
