Geolocation of nodes in Internet using public databases
Sousedík, Tomáš ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This thesis is about host localization using public localization databases in the Internet and related problems. There is basic information how geolocation in general works extended with some other geolocating methods with focus on the geolocation databases. Where it was possible it was written how databases were created and kept up to date. In practical part is described the process how locating functions were made and what problems appeared. At the end is evaluated the accuracy of the databases and comparison between databases and other methods.

DNS protocol client with a graphical interface suitable for lecturing
Sousedík, Tomáš ; Lattenberg, Ivo (referee) ; Jeřábek, Jan (advisor)
This thesis describes DNS protocol and messages it uses to obtain desired information. The protocol is described from its creation and occasions that caused the creation of the protocol. Later on are discussed multicast capabilities of name resolution this section is focused on mDNS and LLMNR. In the second part is detailed description of the structure of the messages and their useage. In the last part is described the design of the application, which was based on the specifications listed in RFCs. One chapter is devoted to a detailed description of the application and its individual parts. A large part is devoted to the testing. There are also described problems that occurred during application development and their solutions.
