How to reconnect internet on an internet blocked computer?

[ryan49321]

So work has blocked internet access on a computer. Sites beginning in https:// can be accessed ie: Google, yahoo, Wikipedia, Facebook, etc... Not all sites can be accessed with this prefix. I do know that the internet can be reconnected when a new DNS address is entered on IPv4.

Any help on the technique they used to limit access?

Try doing a system restore to a date before it was blocked.
