• What is IP Management?

– Configuring network nodes with IP address, mask, gateway, etc.

– Monitoring address usage to ensure efficient deployment

– Configuring DNS servers with each node’s name and IP address

• Why is it needed?

– If hosts can’t get an IP address via DHCP or resolve host names via DNS, they can’t communicate!

– Manual tracking of IP names and addresses cumbersome and error-prone even for moderately sized networks

– Home-grown or freeware solutions lack support

– Spreadsheets don’t scale and lack IP services automation

Marketplace Dynamics-The Analyst Perspective

IP Address growth has outpaced 3M IP hosts/month over the last three years

• A surge in demand for IP addresses for end-‐users and enterprise telephony will raise enterprises’ demand for IP address management

• Adoption of VPN, mobility, and other IP services drives the need to effectively manage IP space

• Deployment of enhanced broadband services will lead to a boom in IP address demand and management complexity

• Regulatory agencies require auditing of IP address space

Internet Protocol Basics



Network Mask

Number of bits in mask = 26

Number of bits in Host ID = 32 - 26 = 6

Fun Facts

• Routers “route” based on the network portion

• On network, resides host

• By increasing the mask, one creates additional “subnets”

• But each subnet has fewer hosts/subnet

Why Not Assign a Static IP Address and Be Done With it?

• Dynamic Address Assignment Benefits

• Mobility

• Resource pooling

• Automation

The Importance of IP Address Services

Automation of IP Address Services is crucial

• IP Address Assignment via DHCP

• Class of Service requirements based on source IP address

• Policy Management for IP Address Space

Manually configuring every machine on your network is a nightmare!!!

DHCP Basic Concepts

• DHCP provides a mechanism to send IP address and parameters to an IP host

• It is a superset of the older BootP protocol

• No foreknowledge of the IP host’s configuration required

• Client/Server implementation

• Activation of DHCP client code on the IP host only

• Defined completely in two IETF RFCs

– RFC 2131

– RFC 2132

The Importance of Name Services

• Name Services is analogous to telephone directories

– In order to communicate via the telephone, the caller must know the telephone number of the person they are calling

– A telephone directory or telephone book provides a lookup between a name and their respective telephone number

Domain Name System Concept

• DNS uses a hierarchical name space

• Responsibility of the name space is distributed

• The Internet is a network of interconnected, but autonomous organizations, each of which are given:

– A unique IP network address so that they could be reached on the Internet

– A unique domain name to make it easier to identify this organization within the context of the more complicated network number addressing scheme

– The responsibility of maintaining the names within that unique address and name

– Both are assigned by agencies under the control of the governing bodies of the Internet

Problems with IP Name & Address Services

• Name and address solutions implemented as point solutions

• Historically implemented on Unix; inherently complex and syntactically difficult to code

• Much manual record keeping

– DNS is statically defined and manually maintained

– DHCP still requires management of the address space

• Information duplicated between services (DNS, NIS, Host Files)

• Requires much coordination within the organization

IP Management Business Challenges

• Continuous Uptime ‐ Provide name & address service continuity

• Accurate IP Inventory ‐ Reduce IP assignment errors

• Automation ‐ Control operating expenses

• Increase Revenue ‐ Offer additional value‐added services

• Maximize ROI ‐ Reduce costs and leverage software investment across services and organizations

Manual Tracking

• Address management based on paper or spreadsheets cannot handle frequent workstation moves or mobile users

• Today’s dynamic networks require automated systems for managing IP addresses

• Staffing and expertise are significantly limited

• Need intelligent platform to offer more advanced network services such as policy based services

Why Automate Address Management?

• Provides a foundation for policy-­‐based network management

– Network managers need to be able to define policies in terms of high-­‐level objects, not device addresses

• Manage the dynamic nature of today’s networks

– Handle moves and changes of personnel

– Handle mobile users

– Handle mergers and acquisitions, new facilities

• Reduces likelihood of human error in data entry and device configuration

• Work effectively in distributed environment
