IP Addresses

Internet Protocol (IP) addresses serve as the feelers upon which the Internet is able to connect computers and servers across great distances and within complicated clusters. These IP addresses come in two forms, IPv4 and IPv6: Example IPv4 address: 180.20.23.162 Example IPv6 address: 2001:0db8:0000:0042:0000:8a2e:0370:7334

IPv6 was built to overcome the eventual exhaustion of available IPv4 addresses, but that hasn't largely happened yet, so our focus here in on IPv4.

How to Determine the Location of an IP Address

Step 1 - Split IP address into four octets

> IP_split("180.20.23.162")

         [,1] [,2] [,3] [,4]
ip.split  180   20   23  162

Step 2 - Calculate IP Integer from Octets

• By hand:

> Octet1 = 180
> Octet2 = 20
> Octet3 = 23
> Octet4 = 162
> (Octet1 * 256^3) + (Octet2 * 256^2) + (Octet3 * 256^1) + (Octet4 * 256^0)

[1] 3021215650

• Function:

> IP_integer("180.20.23.162")

[1] 3021215650

Step 3 - Lookup IP Integer in a Database

> IP_lookup(3021215650)

[1] "China"

IP_country - Convert IP address to country name

• All of the above in one simple function
• Powered by data.table

> IP_country("180.20.23.162")

[1] China
Levels: China

IP_location - Convert IP address into detailed location

• Produces dataframe with country abreviation, country name, region, city, zip code, latitude, longitude, and GMT
• Requires download of a larger database to operate, will prompt you to download an R package on Github (https://github.com/gitronald/ip2locationData/blob/master/data/ip2location.lite.db11.rda) containing the data (~40 MB) if you haven't used the function before.

> IP_location("180.20.23.162")

  abrv country  region    city    zip     lat      long    gmt
1   CN   China Beijing Beijing 100006 39.9075 116.39723 +08:00

IP_plot - Convert IPs to countries and plot on world map

• Enter IPs, get a map with gradient coloring reflecting the percentage of IP addresses originating in each country

> IP_plot(IPs)

IP_generator - Generate random IP addresses

• Generate five random IP addresses

> IP_generator(5)

[1] "125.65.50.53"    "79.250.76.62"    "142.245.152.177" "230.76.201.42"   "107.182.57.171" 

Speed
