    Study Notes

    Internet Fundamentals

    • Internet is a specific method for data transmission
    • Key components of internet management include:
      • Protocols for data transmission (packet switching, TCP/IP, HTTP)
      • IP addresses and corresponding domain names
      • Root servers

    TCP/IP

    • TCP/IP are fundamental communication protocols for connecting network devices on the internet
    • They can also be used in private networks (e.g., intranets, extranets)
    • TCP handles data processing and application handling
    • IP manages network-oriented data transmission and reception

    HTTP

    • HTTP (Hypertext Transfer Protocol) is the application protocol that forms the basis of the World Wide Web
    • It uses logical links (hyperlinks) between texts to create structural hypertext
    • HTTP facilitates data exchange or transfer of hypertext
    • The protocol operates on a request-response principle
    • A client (node) sends a request to a server, which responds with relevant information (e.g., website content).

    Domain Names

    • Domain names are user-friendly translations of numerical IP addresses
    • They improve memorability and understandability compared to IP addresses
    • Domain names have mnemonic functions
    • Domain names also function as a cataloging system that facilitates network management

    Domain Names (cont.)

    • Each domain name is unique
    • It does not need to be associated with a single consistent IP number
    • It should map to a particular IP number or a set of numbers
    • Domain names have two main parts:
      • Top-Level Domain (TLD)
      • Second-Level Domain (SLD)
    • Potentially huge amount of domain name strings based on available characters
    • May include a third-level domain, usually between two and five levels
    • The character set for domain names is under development (e.g., internationalized domain names)

    Top-Level Domains (TLD)

    • Two main classes of TLDs:
      • Generic TLDs (.com, .net, .org, .gov, .edu, .mil, .int, .info, .biz)
      • Country Code TLDs (.it, .fr, .au, .ru, .uk)
    • Sponsored TLDs are also available (.cat, .mobi)

    Domain Naming restrictions

    • Some generic TLDs are restricted (e.g., .pro for professionals, .name for individuals, .gov for government institutions)

    Domain Name System (DNS)

    • Essentially is a system for mapping, assigning, and registering domain names
    • Translates domain names into numerical IP addresses
    • Analogous to a telephone directory that maps names to phone numbers
    • Ensures all parts of the Internet can find each other by converting domain names to numerical IP addresses

    DNS Architecture

    • DNS is a distributed database
    • Holds information on which domain names map to IP numbers
    • Data files are known as roots, stored on root servers
    • Servers are hierarchically ordered, with top servers holding master files for specific top-level domains
    • New TLD additions are managed by ICANN

    ICANN (Internet Corporation for Assigned Names and Numbers)

    • Non-profit organization responsible for coordinating maintenance and procedures of Internet namespaces
    • Ensures stable and secure Internet operation
    • Independent organization handling various aspects of the Internet
    • ICANN has shifted from government oversight to multi-stakeholder governance

    Domain Name Issues

    • Allocation of domain names to persons/organizations
    • Types of TLDs that are permitted

    Domain Name Conflicts

    • Domain names have changed their function: evolving from identifiers to broadly defining ones and carrying value (e.g., trademarks)
    • They are also considered scarce resources in the economic sense
    • Several have acquired high economic value; hence, recognition as a form of property

    DNS Governance

    • Primarily based on contracts
    • IANA (Internet Assigned Numbers Authority), a department of ICANN, handles the allocation of gTLDs
    • ICANN and regional internet registries oversee the allocation of IP numbers

    Contractual Agreements (DNS Governance)

    • ICANN creates contracts/agreements with relevant entities for network stability
    • Establishes policies for allocating IP number blocks
    • Coordinates assignments of other technical parameters for maintaining internet connectivity
    • Guarantees internet stability
    • Determines policies for assignment of DNS to users

    Internet Governance Conclusions

    • No specific regulations for DNS and IP address systems by national legal bodies
    • Internet infrastructure and management mainly self-governed
    • EU Directive 2002/21/EC recognizes Internet naming and addressing autonomy

    ePrivacy Concerns

    • Sharing personal information (name, address, credit card numbers) when using online services like banking, social media, or booking flights
    • Issues surrounding data handling, protection from misuse, and individual rights

    Personal Data Protection

    • All legal systems recognize the protection of personal data
    • Data gathering, storage, and use are regulated under strict conditions
    • Focus on data protection regulations, particularly concerning users' interests
    • The concept of consent in data usage is highlighted

    Conflicts of Interest

    • Users want confidential data use, while service providers seek extensive data collection and use
    • This balancing act of interests is critical in data protection
    • Laws prioritize balancing interests in data collection
