Function for retrieving own ip address from within R?

Does anyone know of an R function that is able to retrieve one's own IP address (of the PC you're working on)? It would be very helpful! Many thanks in advance.

Though @andrie explained it in very layman language and i am sure it helped us a lot to understand the functionality of it.

So from there only sharing a one liner code without installing any other package.

gsub(".*? ([[:digit:]])", "\\1", system("ipconfig", intern=T)[grep("IPv4", system("ipconfig", intern = T))])

Hope this would be helpful!

I recently created a minimal package using ipify.org to do this exact thing.

Usage is easy, you can install using devtools and github.

library(devtools) install_github("gregce/ipify")

once installed, its as easy as loading the library and one function call...

library(ipify) get_ip()

This retrieves exactly what you want:

system('ipconfig getifaddr en0')

You can issue a system() command to your operating system:

  • In Windows you can use ipconfig
  • In Linux, use ifconfig

For example, on Windows try calling system() with the argument intern=TRUE to return the results to R:

x <- system("ipconfig", intern=TRUE)

This returns:

x

[26] "Tunnel adapter isatap.tbglondon.local:"                             
[27] ""

[33] "   Media State . . . . . . . . . . . : Media disconnected"          
[34] "   Connection-specific DNS Suffix  . : "

Now you can use grep to find the lines with IPv4:

x[grep("IPv4", x)]
[1] "   IPv4 Address. . . . . . . . . . . : 10.201.120.184"
[2] "   IPv4 Address. . . . . . . . . . . : 10.201.120.157"

And to extract just the ip address:

z <- x[grep("IPv4", x)]
gsub(".*? ([[:digit:]])", "\\1", z)
"10.201.120.184" "10.201.120.157"
