IPAM and UDT have combined like Voltron to form the new IP Control Bundle and as an IT "pro-", you may finally say goodbye to the painful and long IP Address Conflicts troubleshooting. Say goodbye to the long down-time of your servers, key network infrastructure or disconnected end users, caused by duplicated IP address on your network. For new users IPAM 4.3 and UDT 3.2 are now also available as a combo of two products with "in-line" integration focused on IP Address Conflict troubleshooting. For our existing customers both new versions act as regular product upgrade. There is no difference in functionality between bundle and standalone versions.
What IP Address conflicts it detect?
1) Static IP Address assignment on two end-points within the same network
Typical situation when this may happen is cloning virtual machines. People simply download or copy virtual image and run it within the network not knowing if there is static IP address pre-set.
2) Static IP in DHCP environment
There is many situations when static IP address may cause conflict within dynamic (DHCP driven) network. It can be somebody's laptop with static IP from the hotel, it can be cloned virtual machine with static IP, it can be attacker who is trying to connect to local network using static IP Address. It also can be newly connected network printer which has usually default static IP from private pool of IP address range - 192.168.x.x
3) DHCP scope overlap (split-scope)
DHCP scope overlap problem can occur these days much more frequently because local networks are usually controlled through DHCP servers and if DHCP server goes down, nobody can get new IP Address and connect to the network. from that reason, IT build backup or fail-over solution which consist from two or more DHCP servers. It's usually DHCP config misconfiguration or DHCP failure which cause both DHCP servers can provide the same IP address to two totally different devices.
4) IPAM end-point reservation vs. actually connected device
In a case IT admin reserved IP address to the specific end-point (MAC address) and other device is currently connected with that IP it doesn't really mean, there is a real IP address conflict. This may be because of obsolete IPAM information, or an upgrade of originally assigned device. However, it could be just a time bomb waiting for the reserved device to be connected back to the network. In all cases, IPAM administrator should be notified about such situation and either update IPAM reservation or change IP address of unexpected device.
How can IP control bundle help you to solve IP Address Conflicts?
By two clicks you will get the most important information about conflict:
1) Who is in the conflict? MAC addresses, Vendor, Active Directory Information and connected port or Wireless SSID (UDT functionality)
2) History of end-points connection - who is assigned to the IP Address? Show recent user of given IP Address so IPAM admin can understand who should be disconnected first.
3) "How-To" steps helping you do an action
Here is an example of DHCP scope overlap and how IPAM and UDT can help you to troubleshoot the problem:
Both IPAM 4.3 and UDT 3.2 are now ready on customer portal and waiting for your download and upgrade. If you don't have one of these product, or if you would like to evaluate entire IP Control Bundle, you may download it for evaluation.
IPAM and UDT also brings other improvements and bug fixes, for more details, see our release notes for IPAM and UDT.
I can recommend you to watch following web-cast we made recently, which not only summarizes IP Address Conflict issues but also compares multiple IP Address Management solution and demonstrates latest IPAM & UDT (IP Control Bundle).
