thanks jim...
there is another way...the country road way
char inputIpstring[16];
int oct1,oct2,oct3,oct4,
sscanf(inputIpString,"%d.%d.%d.%d",&oct1,&oct2,&oct3,&oct4)
increment anyof the octetes as you want and
sprintf(inputIpString,"%d.%d.%d.%d",oct1,oct2,oct3,oct4);
BTW, if I pass 225.10.20.30 and would need all the Ip addresses from 225.10.20.30 to 225.10.30.30 without the last octet being changed....that is
225.10.20.30
225.10.21.30
225.10.22.30
225.10.23.30
225.10.24.30
etc...
willt his work with the inet_addr() method,
Would I add 510 and I will get 225.10.21.30 from 225.10.20.30?

SYNOPSIS
bool socket_connect (resource $socket, string $address, [int $port])
DESCRIPTION

PARAMETERS
o $socket
-
o $address
- The $address parameter is either an IPv4 address in dotted-quad notation (e.g. 127.0.0.1) if $socket is AF_INET, a valid IPv6
address (e.g. ::1) if IPv6 support is enabled and $socket is AF_INET6 or the pathname of a Unix domain socket, if the socket fam-
ily is AF_UNIX.
o $port
- The $port parameter is only used and is mandatory when connecting to an AF_INET or an AF_INET6 socket, and designates the port
