`pythonwhois` does not yet support WHOIS lookups on IP ranges (including single IPs), although this will be added at some point in the future. In the meantime, consider using [`ipwhois`](https://github.com/secynic/ipwhois) - it offers functionality and an API similar to `pythonwhois`, but for IPs. It also supports delegated RWhois.
Do note that `ipwhois` does not offer a normalization feature, and does not (yet) come with a command-line tool. Additionally, `ipwhois` is maintained by Philip Hane and not by me; please make sure to file bugs relating to it in the `ipwhois` repository, not in that of `pythonwhois`.
*2.4.0 and up*: A lot of changes were made to the normalization, and the performance under Python 2.x was significantly improved. The average parsing time under Python 2.7 has dropped by 94% (!), and on my system averages out at 18ms. Performance under Python 3.x is [unchanged](https://github.com/joepie91/python-whois/issues/27). `pythonwhois` will now expand a lot of abbreviations in normalized mode, such as airport codes, ISO country codes, and US/CA/AU state abbreviations. The consequence of this is that the library is now bigger (as it ships a list of these abbreviations). Also note that there *may* be licensing consequences, in particular regarding the airport code database. More information about that can be found below.
*2.3.0 and up*: Python 3 support was fixed. Creation date parsing for contacts was fixed; correct timestamps will now be returned, rather than unformatted ones - if your application relies on the broken variant, you'll need to change your code. Some additional parameters were added to the `net` and `parse` methods to facilitate NIC handle lookups; the defaults are backwards-compatible, and these changes should not have any consequences for your code. Thai WHOIS parsing was implemented, but is a little spotty - data may occasionally be incorrectly split up. Please submit a bug report if you run across any issues.
*2.2.0 and up*: The internal workings of `get_whois_raw` have been changed, to better facilitate parsing of WHOIS data from registries that may return multiple partial matches for a query, such as `whois.verisign-grs.com`. This change means that, by default, `get_whois_raw` will now strip out the part of such a response that does not pertain directly to the requested domain. If your application requires an unmodified raw WHOIS response and is calling `get_whois_raw` directly, you should use the new `never_cut` parameter to keep pythonwhois from doing this post-processing. As this is a potentially breaking behaviour change, the minor version has been bumped.
Be aware that the OpenFlights database in particular has potential licensing consequences; if you do not wish to be bound by these potential consequences, you may simply delete the `airports.dat` file from your distribution. `pythonwhois` will assume there is no database available, and will not perform airport code conversion (but still function correctly otherwise). This also applies to other included datasets.
Feel free to fork and submit pull requests (to the `develop` branch)! If you change any parsing or normalization logic, ensure to run the full test suite before opening a pull request. Instructions for that are below.
