(Works obviously for every other TLD as well<\/em>)<\/p>\n\n\n\n

As the new TLDs from Google already intend to be misused for shady phishing attacks and on the other side we can’t imagine any non-shady usage for those domains, we’ve decided to block those entirely. <\/p>\n\n\n\n

We show you, how we’ve done that:<\/h3>\n\n\n\n

On the Windows DNS-Server (mostly the Domain Controller) we create a new Forward Lookup Zone:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

We select “Primary zone”:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

As “Zone name” we set the TLD to block, for example “zip” – Make sure to not add any points:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Next settings are fine already:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

And this setting is fine by default, too:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

By clicking on “Finish”, we create the zone:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Now, it should look somehow like this in Forward Lookup Zones:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

In each zone we now create an A- and an AAAA-Record with * as host und localhost as target:<\/p>\n\n\n\n

\n
\n
\"\"<\/a><\/figure>\n<\/div>\n\n\n\n
\n
\"\"<\/a><\/figure>\n<\/div>\n<\/div>\n\n\n\n

… so it should look like this:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

As soon as we created the records, every machine using this server as DNS-source should resolve names with those TLDs locally, so it’s only connecting to itself.<\/p>\n\n\n\n

You could even go further to create a landing page on a webserver for those Domains – but this requires more configuration as you’d get a certificate warning when accessing with https:\/\/. So you would have to create a Wildcard-Cert on an internal CA as well.<\/p>\n","protected":false},"excerpt":{"rendered":"
