We delete these temporary logs within 24 to 48 hours.

In the permanent logs, we don’t keep personally identifiable information or IP information. We do keep some location information (at the city/metro level) so that we can conduct debugging, analyze abuse phenomena and improve the Google Public DNS prefetching feature. We don’t correlate or combine your information from these logs with any other log data that Google might have about your use of other services, such as data from Web Search and data from advertising on the Google content network. After keeping this data for two weeks, we randomly sample a small subset for permanent storage.

Finally, if you’re interested in knowing what else we log when you use Google Public DNS, here is the full list of items that are included in our permanent logs:

* Request domain name, e.g. http://www.google.com
* Request type, e.g. A (which stands for IPv4 record), AAAA (IPv6 record), NS, MX, TXT, etc.
* Transport protocol on which the request arrived, i.e. TCP or UDP
* Client’s AS (autonomous system or ISP), e.g. AS15169
* User’s geolocation information: i.e. geocode, region ID, city ID, and metro code
* Response code sent, e.g. SUCCESS, SERVFAIL, NXDOMAIN, etc.
* Whether the request hit our frontend cache
* Whether the request hit a cache elsewhere in the system (but not in the frontend)
* Absolute arrival time in seconds
* Total time taken to process the request end-to-end, in seconds
* Name of the Google machine that processed this request, e.g. machine101
* Google target IP to which this request was addressed, e.g. one of our anycast IP addresses (no relation to the user’s IP)

Dite che non userà i log per ricerche di mercato?
Buona giornata a tutti!

può essere interessante e potete provarci anche voi

-Fai clic destro sull’icona della connessione di rete
-Apri “Centro connessioni di rete e condivisioni” (lo trovi anche sul Pannello di controllo) e clicca su “Visualizza stato”
-Dalla finestra che si è aperta clicca su “Proprietà” (se rompe le scatole l’UAC dai il permesso.. )
-Seleziona dalla nuova finestra il protocollo TCP/IPv4 e apri le “Proprietà”
-Da quest’ultima finestra puoi modificare DNS con “Utilizza i seguenti indirizzi server DNS”

Server DNS predefinito: 8.8.8.8
Server DNS alternativo 8.8.4.4

-Infine dai l’OK per confermare.

In questo modo utilizzerai i nuovi DNS di Google su Windows.

-Apri il terminale e digita:

sudo gedit /etc/resolv.conf

-All’inizio del file, inserisci queste due righe:

nameserver 8.8.8.8
nameserver 8.8.4.4

-Infine salvi e chiudi Gedit.

In questo modo utilizzerai i nuovi GoogleDNS su Ubuntu.
