+### canonicalize_url
+
+Function returning a clean and safe version of the url by performing the same kind of preprocessing as web browsers.

+### fingerprint_hostname
+
+Function returning a "fingerprinted" version of the given hostname by stripping subdomains irrelevant for statistical aggregation. Be warned that this function is even more aggressive than [normalize_hostname](#normalize_hostname) and that the resulting hostname might not be valid anymore.
+
+```python
+from ural import fingerprint_hostname
+
+fingerprint_hostname('www.lemonde.fr')
+>>> 'lemonde.fr'
+
+fingerprint_hostname('fr-FR.facebook.com')
+>>> 'facebook.com'
+
+fingerprint_hostname('fr-FR.facebook.com', strip_suffix=True)
+>>> 'facebook'
+```
+
+*Arguments*
+
+* **hostname** *string*: target hostname.
+* **strip_suffix** *?bool* [`False`]: whether to strip the hostname suffix such as `.com` or `.co.uk`. This can be useful to aggegate different domains of the same platform.
