DNS servers, we surf the Internet using names such
as "www.nicgrab.com" instead of impossible to
remember IP addresses. DNS servers translate these
domain names into machine readable IP-addresses
needed to locate the requested web-server on the
Internet. With Simple DNS Plus you can hosts your
own domain name, or simply speed up Internet
access by running your own DNS server. Simple DNS
Plus can easily be integrated with your web-site
for ISP customer signup etc., or even a full
web-based DNS solution. Simple DNS Plus is also a
DHCP server, it comes with a DNS Look Up tool, and
many other features...

||Run your own Internet DNS
If your computer already has a fixed IP-address -
for example if you have a cable modem, DSL or
another permanent Internet connection - why not
also get a real identity...
Speed up Internet access with
Even if you don't have your own domain name,
Simple DNS Plus will speed up Internet access by
caching all DNS records requested by your computer
(or network of computers) locally, and fetching
them again later much much faster.
Name the computers on your LAN
and forget IP addresses and hosts files
Tired of maintaining lists of IP addresses or
manually updating and copying hosts files on your
local network ?
With Simple DNS Plus, you can call your
e-mail-server "mail", your proxy-server "proxy",
your Intranet web-server "web", etc. Then use
these easy to remember names instead of IP
addresses when setting up your client PCs'
Internet programs, and you never have to edit a
hosts file again.
Integrated DHCP server auto
configures network computers and DNS
IP-addresses and other TCP/IP options can
automatically be assigned to your network
computers through DHCP.
Client computers configured through DHCP are
automatically registered as DNS records, so the
rest of the network can easily locate them.
There simply is no easier way to configure a DNS
server - or TCP/IP settings on your network
Simple DNS Plus also has a unique feature fixing
the "unkown DHCP client" problem often encountered
with older Apple/Mac DHCP clients.
Automate secondary DNS servers
A secondary Simple DNS Plus server can be
configured as a "slave" server, meaning that all
updates on the primary server are automatically
transfers to the secondary. This includes creating
and deleting zones.
(On other DNS server, you have to create and
delete zones on both primary and secondary
Everything is completely automated - when changes
are made in the Record Editor, Simple DNS Plus
immediately notifies secondary servers and a Zone
Transfer is initiated.
Simple DNS Plus can also be configured as a
standard secondary DNS server, and will then
automatically check for updates on the primary
As everything else in Simple DNS Plus, Zone
Transfers are implemented according to the DNS
standards (RFCs), and so it is 100% compatible
with other standard DNS servers.
DNS Spoofing Security option
"DNS spoofing" is a term used for malicious cache
poisoning where forged data is placed in the cache
of DNS server.
Spoofing attacks can cause serious security
problems, for example causing users to be directed
to wrong Internet sites or e-mail being routed to
non-authorized mail servers.
With the spoofing security option enabled, all
records in received DNS answers are checked for
authority, and records for which the answering DNS
server does not have authority are ignored.
"Round Robin" Load distribution
If you have multiple web servers (or other
Internet servers), containing identical content,
Simple DNS Plus can automatically distribute
connection loads across the servers using Round
Round Robin works on a rotating basis in that one
server IP address is handed out, then moves to the
back of the list; the next server IP address is
handed out, then it moves to the end of the list;
and so on, depending on the number of servers
Easy to use GUI interface -
forget cryptic DNS configuration files
Simple DNS Plus provides three simple ways to
configure the IP/Domain Name mappings:
- Use the intuitive GUI interface and wizards
which guide you through what to enter where, and
automatically checks for and corrects most errors.
- Enable DHCP, and both client computers and DNS
records are configured completely automatic
without the need for any further intervention.
- Use your existing Windows hosts file. Many users
are already familiar with this file and it's
- Any combination of above.
DNS Look Up tool - including
Great for testing your installation and
troubleshooting all kinds of network problems.
With the "WHOIS" feature, you can check the
details (such as name, address and phone) on the
owners of a domain name or IP address.
Reverse Zone Wizard
Forget "in-addr.arpa" and reversing IP address
With the "Reverse Zone Wizard", you simply specify
your IP address range and Simple DNS Plus
automatically generates all the necessary records.
It even supports "classless delegation" for those
with less than 256 IP addresses.
Pre-load of Root DNS server
Simple DNS Plus pre-loads the Internet root DNS
server records at startup.
This makes it possible to completely bypass your
ISP's DNS servers which in many cases may be slow.
For intranet DNS servers, you can define your own
root records through the GUI interface.
Integrate with other
Simple DNS Plus can automatically check for and
load new zone files (DNS record files) generated
by other applications, and also includes an
interface (TCP/IP) for other applications to
control loading and unloading of records.
HTTP administration /
Create a web interface to your DNS server for
yourself or yours customers.
This is ideal for communicating with Simple DNS
Plus from other applications across the network
(for example ASP scripts running on IIS).
Support for Windows 2000
Windows 2000 clients can register themselves in
the DNS database.
(IP address permission list per zone).
Incremental Zone Transfers
A history of individual record updates (DHCP,
dynamic update, HTTP updates) is recorded, so
secondary DNS servers don't need to zone transfer
the entire zone each time there is a change.
This saves both CPU cycles and bandwidth.
This function makes it very simple to import zones
from other DNS server implementations.
This includes zone transfer, import zone file, and
import set of zone files based on a boot file.
Support for wildcard records (
If you are hosting many sub-domains on the same
servers, this feature can be a real time saver.
Standard "Master File" format
Simple DNS Plus uses the standard file format
defined in the RFCs, and can use standard files
from other DNS implementations including different
UNIX and Bind DNS servers.

Optional detailed log files
Simple DNS Plus optionally writes all DNS queries
and answers to a log file which you can then
analyze at your convenience.
Domain usage statistics
With the raw log parser utility, you can
create statistics for your own internal use or
make it available on-line with bar charts etc.
Animated Tray Bar Icon.
Simple DNS Plus resides in the tray-bar (next to
the clock), so it is out of the way, but always
within a click's reach.
The Tray Bar Icon lights up whenever Simple DNS
Plus is processing requests, so you will know even
when the program is minimized.
