  1. Windows Server 2012 IP Address Management Clyde Johnson President Boston Area Windows Server User Group

  2. IPAM (Internet Protocol Management) • Planning, tracking and managing • Increasingly important as new IPv6 networks are deployed • Wikipedia has over 26 vendors in this space. • New feature of Windows Server 2012

  3. Examples of IP Address Management Problems • I need to change a DHCP option like web proxy across dozens of scopes residing on multiple servers… • I am adding a new lab and want to assign subnets from my address plan… • I need to track user or machine activity in my network for troubleshooting or forensics… • I want to track my org’s address space and know addresses in use and available across different locations… • I have to find a free IP address for a new device and register it in DNS … • A DHCP Scope is full and clients are not getting any addresses – I need to expand the scope or create a firefighting scope…

  4. IPAM Options . Spreadsheets . In-house tools Commercial appliances . . . • No CapEx investment • Simple to use for small networks….at first • Automation • High degree of customization • Automation • Rich feature set • Integration with own and MS DHCP/DNS . . • Labor intensive estimated (~$10 per address per annum) • Only performs address mgmt. • Inflexible and does not scale . Cons Pros • Maintenance cost • Relies on in-house support model • Expensive to add new capabilities • High acquisition and support costs

  5. Windows Server 2012 IPAM Overview Organize, assign, monitor and manage static and dynamic IPv4/v6 addresses Address space mgmt (ASM) Network discovery . Automatic discovery of DC, DHCP and DNS servers, and dynamic IP addresses in use In-box solution that complements – and seamlessly integrated with – MS DHCP and DNS offerings WS 2012 IPAM Multi-server mgmt (MSM) . Centralized configuration and update of MS DHCP/DNS servers Visibility & audit Track and audit changes and provide real-time view of status

  8. IPAM Installation • Installed as a feature of Windows 2012 • Cannot provision on a domain controller

  9. IPAM Collections • IP addresses, client identifiers, and host names are collected from lease logs on managed DHCP serversUser names and IP addresses are collected from logon events on managed domain controllers. • User names and client identifiers are collected from logon events on managed network policy servers.

  10. IPAM Queries • Query1: Find all DHCP lease events that match a specified IP address, client ID, or host name.Query2: Correlate network authentication events with the start and end times for events in query 1. • Query3: Display all logon events that match a specified user name with correlated DHCP lease events.
