Introduction
Overview
System of Advanced Medicos Limited (AMS) provides several health services. AML
intends in providing health services by using web along with the system used by them. AML is
looking to upgrade their system. Current network of AML is old and should be replaced. They
want to use latest technologies for their organization with network that could accommodate load
for next few years also. Marketing and software development are inside building A and other
departments are inside building B. Network is switched network having no support of wireless

connection among these two buildings. Access from one building to another building is done by
web portal.
The report attempts in showing that how essential it is in optimizing the networks through
applying IP configuration that is favorable within routers of the business networks. This report
shows the calculation of IP requirements for all departments of building A, building B and
headquarters and how these must be configured. A table is also shown in this report describing
the IP requirements for every department of building A, building B as well as headquarters.
IP Addressing
The table include address spaces that are to be allocated for every branch along with the
headquarters. Address spaces’ optimal allocation is conducted by VLSM subnet calculation. IP
addresses are displayed and written in notations that are readable by human. Size of address’s

routing prefix is designated within CIDR notation through suffixing address through number of
few significant bits.

Production - 10 workstations, 2 printers – a total of 12 IP.
Marketing 5 workstations, 4 printers – a total of 9 IP.
Accounting and Finance 5 workstations, 3 printers – a total of 8 IP.
Administration 5 workstations, 2 printers – a total of 7 IP.
Building A have, Marketing and Software development departments. The marketing and
