A micro-package for getting your IP address, either the local/internal or the public/external one. Currently only IPv4 addresses are supported.

Installation

You can install the stable version from CRAN using the usual `install.packages()

install.packages("getip")

The development version is maintained on GitHub:

remotes::install_github("wrathematics/getip")

Usage

To get your local (internal) IP address:

getip::getip("internal")

To get your public (external) IP address:

getip::getip("external")

The argument is case-insensitive and operates by partial matching. So if you're very lazy, you can just type getip("e") for the external IP.

There are two other exported helper functions. One is validip() which will check if a vector of strings are potentially valid IP addresses (though not necessarily in active use --- i.e., it does not use the internet)

ips = c("127.0.0.1", "25", "255.255.255.255", "255.555.255.1")
getip::validip(ips)
## [1]  TRUE FALSE  TRUE FALSE

The final exported function is hostname2ip(). This returns a list of vectors of IP addresses for a vector of hostnames. This queries the internet.

hosts = c("www.google.com", "localhost", "www.yahoo.com")
getip::hostname2ip(hosts)
## [[1]]
## [1] "64.233.185.103" "64.233.185.99"  "64.233.185.147" "64.233.185.106"
