New Internet Services Based on the Ever-Evolving DNS
The domain name system (DNS) is an important basic technology that
has supported the Internet since the establishment of its specifications.
While it continues to evolve, new Internet services will be created,
and it is predicted that various technologies will emerge in the near
future. With these new technological developments, the role and application
of the DNS are expanding. How is it changing, and in what part? Which
parts of it remain unchanged?
This article helps you to understand
all the important aspects of the DNS, from the basics to the mechanisms
of new services.
Part 1: History
Offering new services by expanding the framework rather than changing
it
Part 2: Fundamentals
Managing information by distributing it to servers within a single
tree hierarchy
Part 3: New Services
Understanding the latest services that are already being actively used
Japanese Domain Names/Dynamic DNS
Part 4: Leading-Edge Technology
Anticipating pioneering technologies that will debut in the near future
ENUM/Identification of Email Senders/Compatibility with IPv6
FEATURE 2
A Clear Grasp of “Ultimate” Authentication Technology
through a Q&A Format
The Overall picture of IEEE802.1X
- IEEE802.1X appears in newspaper and magazine articles as a keyword
on issues such as the security of wireless LAN and quarantine networks.
It is a technology for authenticating users in a LAN, but it may not
be known to many people.
This article presents an outline of IEEE802.1X
by answering simple questions about it.
Part 1: Basic Technology
Mechanism of IEEE802.1X: Three main functions support authentication
Part 2: Methods for Authentication
Various Methods for Authentication: Wireless LAN requires the use of
ciphers
Part 3: Establishment and Operation
Connection to Hubs and Printers: It is necessary to check issues for
smooth operation
