Checking range of ips
Given a range of IPs similar to this:

Code:
"212.63.183.19","212.63.183.19","3560945427","3560945427","CN","China"
"217.7.143.0","217.7.143.0","3641151232","3641151232","CN","China"
"218.0.0.0","218.31.255.255","3657433088","3659530239","CN","China"
"218.56.0.0","218.99.255.255","3661103104","3663986687","CN","China"
"218.100.88.0","218.100.255.255","3664009216","3664052223","CN","China"
"218.104.0.0","218.109.255.255","3664248832","3664642047","CN","China"
"218.185.192.0","218.185.223.255","3669606400","3669614591","CN","China"
"223.165.4.0","223.165.7.255","3752133632","3752134655","ID","Indonesia"
"223.165.8.0","223.165.15.255","3752134656","3752136703","TW","Taiwan"
"223.165.16.0","223.165.19.255","3752136704","3752137727","NZ","New Zealand"
"223.165.20.0","223.165.23.255","3752137728","3752138751","JP","Japan"
"223.165.24.0","223.165.31.255","3752138752","3752140799","IN","India"

How do you find out which country the below IP belongs to?

Code:
218.30.103.106

some awk or grep command can probably be used here. but i'm hoping someone with some knowledge on IPs can shed light on the proper way to do this.

i'm going to have a list of specific IP addresses and i need to figure out under which country they correspond.

Convert the quad-dotted ip address to decimal and check if it falls within the inclusive range specified by the third and fourth columns in your file (which are the decimal equivalents of columns 1 and 2).
Code:
A.B.C.D = A*2^24 + B*2^16 + C*2^8 + D

Here's the easy route:

Code:
curl http://api.hostip.info/get_html.php?ip=218.30.103.106
Country: CHINA (CN)
City: (Unknown city)
IP: 218.30.103.106

thank you so much. this was actually my original option. but, i had to take into account the possibility of the site (api.hostip.info) not being up 100% of the time (not that it has ever been an issue in the past). but i have to account for that. i like this option. its pretty straightforward.

was just wondering if there's another way to get this information from a list that contains the range of IPs and their countries, which is what i pasted in my first post. this list will be on my local server which is guaranteed to be available 100% of the time.

Here is a quick and dirty awk script
Code:
awk -F, -v I="218.30.103.106" '
function ip2dec(ip, slice) {
    gsub(/"/,"",ip)
    split(ip, slice, ".")
    return (slice[1] * 2^24) + (slice[2] * 2^16) + (slice[3] * 2^8) + slice[4]
}
ip2dec(I)>=ip2dec($1) && ip2dec(I)<=ip2dec($2){print $6}' country.txt

thank you so very much. i would not have been able to figure this out on my own. and i really really really appreciate you taking the time.

you wouldn't happen to know of a way to make the script run faster, would you? the Country.txt file is about 6MB in size. and to check one IP took about 2-3 seconds. i intend to run your script on a hundreds of IPs. so it'll be great if there's a way to make it fast.

again. thank you so much for this!!!
