Abstract
A method and a device for notification, by a notification device, of the use by at least one terminal of an uncertified domain name server. The method includes: receiving a request from the at least one terminal, the request comprising at least one parameter corresponding to a first address enabling communication with a server; searching for the first address in a list, the list comprising at least one address obtained from at least one certified domain name server; and notification, according to the search result, of the use by the at least one terminal of an uncertified domain name server.
Claims15
A method for providing a notification, by a notification-providing device, of use by at least one terminal, of an uncertified domain name server, the method comprising:
- receiving a request from said at least one terminal, said request comprising at least one parameter corresponding to a first address allowing communication with a server;
- obtaining a first list comprising at least one address from at least one certified domain name server of an Internet service provider of the at least one terminal;
- searching for said first address in the first list;
- depending on a result of the searching for said first address, determining that said at least one terminal requested a domain name server resolution from a domain name server that is not a certified domain name server of the Internet service provider of the at least one terminal;
- and
- providing a notification, depending on the result of the searching, to said at least one terminal of said at least one terminal retrieving the first address from an uncertified domain name server.
A device for providing a notification of use by a first terminal of an uncertified domain name server, and wherein the device comprises:
- at least one processor;
- and
- at least one non-transitory computer readable medium comprising instructions stored thereon which when executed by the at least one processor configure the device to:
- receive a request from said first terminal, said request comprising at least one parameter corresponding to a first address allowing communication with a server;
- obtain a first list comprising at least one address from at least one certified domain name server of an Internet service provider of the at least one terminal;
- search for said first address in the first list;
- depending on a result of the searching for said first address, determine that said at least one terminal requested a domain name server resolution from a domain name server that is not a certified domain name server of the Internet service provider of the at least one terminal;
- and
- provide a notification, depending on the result of the search, to said first terminal of said first terminal retrieving the first address from an uncertified domain name server.
A non-transitory computer-readable medium comprising a computer program stored thereon comprising instructions for implementing method for providing a notification of use by at least one terminal of an uncertified domain name server when the program is executed by a processor of a device, the method comprising:
- receiving a request from said at least one terminal, said request comprising at least one parameter corresponding to a first address allowing communication with a server;
- obtaining a first list comprising at least one address from at least one certified domain name server of an Internet service provider of the at least one terminal;
- searching for said first address in the first list;
- depending on a result of the searching for said first address, determining that said at least one terminal requested a domain name server resolution from a domain name server that is not a certified domain name server of the Internet service provider of the at least one terminal;
- and
- providing notification, depending on the result of the searching, to said at least one terminal of said at least one terminal retrieving the first address from an uncertified domain name server.
