The [`iptools` package](https://github.com/hrbrmstr/iptools)—a toolkit for manipulating, validating and testing IP addresses and ranges, along with datasets relating to IP addresses—is flying through the internets and hitting a CRAN mirror near you, soon.

### What’s fixed?

[Tim Smith](https://github.com/tdsmith) fixed [a bug](https://github.com/hrbrmstr/iptools/issues/26) in `ip_in_range()` that occurred when the netmask was `/32` (thanks, Tim!).

### What’s new?

The `range_boundaries()` function now returns the three new fields that are pretty obvious once you see it in action:

range_boundaries("172.18.0.0/28")
##   minimum_ip  maximum_ip min_numeric max_numeric         range
## 1 172.18.0.0 172.18.0.15  2886860800  2886860815 172.18.0.0/28

They are tacked on the end, so if you were using positional or named columns previously, you’re still good to go.

We’ve added a new `country_ranges()` function to return all “assigned” CIDR blocks in a country. You just give it character vector of one or more ISO 3166-1 alpha-2 codes and you get back the CIDRs:

country_ranges("TO")
## $TO
## [1] "43.255.148.0/22"  "103.239.160.0/22" "103.242.126.0/23" "103.245.160.0/22" "175.176.144.0/21" "202.43.8.0/21"   
## [7] "202.134.24.0/21"

This data is updated daily and there’s some session caching built-into the function to speed up subsequent calls if you forgot to save the output. You can flush the session cache with `flush_country_cidrs()` and query it with `cached_country_cidrs()`.

### What’s next?

We’re waiting until the R 3.3.0 Windows toolchain is stable to add in MaxMind ASN lookups. If there are any IP-related functions you need added, drop us an [issue](https://github.com/hrbrmstr/iptools/issues). We’re at nearly 1,700 downloads from the RStudio mirror, which (IMO) is kinda cool for such a niche package. Many thanks to all our users and one more thank you to Dirk for the `AsioHeaders` package.

### Fin

If you want some “bad” IP addresses to play around with in `iptools`, check out the [`blocklist`](https://github.com/hrbrmstr/blocklist) package, which provides an interface to a subset of the [blocklist.de](http://www.blocklist.de/en/index.html) API.
