Transcript IP Address Changes - Instructional Technology of KCS

Oh no! We have new IP
addresses.
Part Trois
By The Network Team
Why did you do this to me?
 New IP addresses should provide enough
addresses for whole herds of devices
 New IP addresses will allow for
organization within the school and will free
BLTC of having to provide addresses for
most traveling folks
 We finished the whole public IP address
transition last spring and it is time to move
forward.
So now what does this all
mean?
In the past, we asked that you add the new
addresses whenever you move around the
school as you help users and their
machines.
Eventually, the older IP addresses will
become unusable.
Also, some sites have had trouble when
there was a mixture of old and new IP
addresses.
KCS IP Address 101
Prior to this issue of IP addresses, your
school had two types of IP addresses.
Public Addresses
Private Addresses
The public addresses were
the numbers that were
66.4.X.X numbers and are
visible to the outside
world. Most schools have
very few of these numbers.
These numbers have been
changed to 96.4.X.X.
The Private addresses
were the numbers that are
10.x.x.x . Most of the
computers in your school
have these addresses.
Each school has at least
four sets of 254 of these
numbers.
The IP Address Anatomy
An IP address consists of four sets of
numbers (octets) separated by a period.
An example of an IP address would be
10.55.7.174
Computers use IP addresses to help find where to send
and receive data. Each computer must have a unique IP
address.
The New IP Address
-The new IP issue allows a huge number of IP
addresses for each school. The first digits will
always be 10.
-The second octet will be the school’s number that
the BLTC was given
-The third octets vary from 7-111 based on what
type class that the computer is in
-The fourth octet will be a number between
1 and 254.
What is the school number?
The second digits (octets) are the numbers
that are set up for each school

Description of current
problems involving IP
addresses
Some folks who have changed computers
from the old 10.145.x.x addresses to the
new 10.xxx.xxx.xxx addresses have found
that they may have trouble printing to
network printers that they used to be able
to print to.
The cause of the problem?
The problem of not being able to connect to
printers and such would be an issue in the
router.
The router provides all of the IP address
information in the school in the form of
files called Routing Tables.
When new Routing Tables were put into the
router, the two routing tables (10.145.x.x
and 10.x.x.x) were not linked together.
The cause of the problem?
Routing and routing tables are handled by
the fine engineers at ENA (Education
Networks of America) in Nashville.
Some of our schools have the routing tables
linked together and some do not. There is
no way for the Network Team to do much
about this but complain.
So,
Be aware that when you change IP
addresses on computers, you might also
change the IP addresses on the printers
too.
To help you we have
documentation. Just ask.
