Networking is IN

• Increasing number of IP addresses (ad hoc
  networks, mesh networks, sensor networks,
  community networks)
• Which of these are likely IP end points
• VoIP Phones
• Cell Phones/PDAs
• Cable/DSL modems
• RFID readers
• Parking Meters
• Advertising signage
• Environment Sensors
• Armed forces equipment ( Soldier is a /48
  network metaphor)
• Cameras

IP Address Management (IPAM) Key Business
Challenges
Maintain central repository of all IP address
information for address management, reporting and
planning. Reduce inefficient fragmented address
space allocation and duplicate IP assignment
errors. Control operating expenses through
automation Provide high network availability for
clients/subscribers through centralized
management of DNS and DHCP infrastructure Offer
additional value-added services to increase
revenue Leverage software investment across
services and organizations to maximize ROI

What is IPAM ?

• IP Address Allocation and Inventory
• Policy and rules based and delegated address
  space allocation.
• Centralized repository of IP address utilization
  for capacity planning, auditing, forecasting.
• IP Address Assignment
• Configuring IP end points with IP address and
  other IP configuration.
• Policy-based dynamic configuration of IP
  parameters.
• Management of DHCP infrastructure from a central
  location.
• Name Resolution
• Management of DNS infrastructure from a central
  location.
• Keeping DNS zone data up-to-date for with changes
  in the IP network.

IPAM Even More Important with IPv6

• Virtually infinite address space
• New and evolving address space allocation rules
• Allocation rules critical to achieve efficient
  routing (route aggregation)
• Auto-configuration in IPv6 makes keeping an
  accurate inventory more challenging
• DNS infrastructure becomes more critical in IPv6
  networks
• More records
• Additional services
• DHCPv6 implementations supporting both stateful
  and stateless modes of IP configuration

IPv6 New IP Management Challenges
Manage IPv6 enabled DNS servers (new
RRs) Efficient mechanisms to update/manage much
larger zones
Name Resolution (DNS)
Integrated Node Mgmt in a dual stack
environment Manage transition points like tunnel
brokers and translators IPv6 roll out planning

IPv6 and Operational Streamlining

• IPV6
• Address space management and allocation
• more rules-based with strict control to ensure
  geospatial route summarization and aggregation
• Hybrid network management (v4 and v6)
•  
• Operational Streamlining
• More robust reporting and planning capabilities
  through capabilities like network discovery
• Tighter integration into business processes to
  reduce cost of ownership (operational costs) by
  orders of magnitude

Role of DHCP and DNS

• Value added address assignment
• Security (Authenticated vs. Quarantined)
• Differentiated access (e.g., Class of service
  based access)
• Integrated end point configuration and firmware
  management
• Extensibility to meet custom needs of VoIP, 3G/4G
  and converging networks. PPP gt DHCP
• Multi-service naming services environment
• ENUM
• ONS in RFID
• More Robust DNS and DHCP
• Higher security prevent DoS attacks
• Better performance and availability
• Appliance based solutions

• Firmware /Business Logic upgrade
• Configuration changes

13
Reconciliation

• Network Discovery
• More devices and services deployed
• Need management system to reflect real network
  configuration
• Perform discoveries to reconcile planned vs.
  actual
• Security
• Enhanced security through knowledge of deployed
  systems and services
• Better able to manage growth of services without
  compromising system and network security

14
Accountability

• Auditing Security
• Increased need to determine who did what, when,
  from where
• System must include ability to track users to
  systems and IP addresses
• Required for compliance with several regulatory
  processes and laws

15
Authentication and Verification

• Security
• Need to prevent viruses from infecting the
  network and unprotected systems
• Allow users and systems to access only approved
  networks
• Prevent data updates from affecting the network
• Flexibility
• Assign IP addresses based on more than just MAC
  address
• New Services
• System Configuration
