  • Converting IP Addresses To And From Integer Values With ColdFusion

    Hi, The problem with your first solution is that for any IP adresse in the upper half of the IPv4 pool (> 128.0.0.1) coldfusion will answer with a negative number, ex: IP Address: 170.112.108.147 IP Number: -1435472749 Coldfusion bit operations are working on 32 bits signed integer,... read more »

    @Ben: yes, however coldfusion bit shifting operate on signed integer, which is not good for this operation. @Tom: Personnally i use the following to convert from dotted decimal to decimal: <cfset ipdec = 0> <cfloop list="#ip_source#" delimiters="." index="i"> <cfset ipdec=ip... read more »

I believe in love. I believe in compassion. I believe in human rights. I believe that we can afford to give more of these gifts to the world around us because it costs us nothing to be decent and kind and understanding. And, I want you to know that when you land on this site, you are accepted for who you are, no matter how you identify, what truths you live, or whatever kind of goofy shit makes you feel alive! Rock on with your bad self!
