PHP's filter_var function can validate if an IP address is valid and can further validate if it is an IPv4 IP, IPv6 IP, or not within the private or reserved ranges. Note that the filter_var() function requires at least PHP version 5.2.0.

get By Namepublic static Inet Address get By Name(String host) throws Unknown Host Exception Determines the IP address of a host, given the host's name.

The host name can either be a machine name, such as "com", or a textual representation of its IP address.

Please use the registration form, to register here or read more information about the registration process. If the user enters 1x.50 it is taking the ascii value of x and taking the IP QString IPaddr; QString List split IP; split IP = IPaddr.split(".");// splitting IP after . So in this split IP i need to check if it contains any character instead of no. ) but this is working if I give 128.88.x45.50 ie character in first field. How can I check the same for QString or std::string Appreciate your help in this regard. This would accept 0.0.0.0 thru 999.999.999.999 where as you could later check the bounds against the input.

Or you could use Reg Exp along with QReg Exp Validator and assign it to the line Edit as well. with 3 dots and only digits are allowed to enter as expected.

to the beginning of the error message as well.The use of in the regular expression is obviously redundant.If a literal IP address is supplied, only the validity of the address format is checked. The get By Name() function will take IP Addresses or DNS names.Is there any function that will only take IP Addresses? I want to do the same thing, but pass a String in the format: [0-255].[0-255].[0-255].[0-255] and have it tell me if the address is within a legal range...Does a function like that exist in the Java API (not 3rd party download)?Something like: I used set Input Mask("0.000"); So it gave my lineedit like .

Hi All, This is a small snippet that I am using to validate the format of IP address. Since this is not elegant, please let me know if anyone has a better working code than the one below.
