Five indicators of a poor performing IPAM infrastructure
I’ve seen hundreds of customer architectures and spoken with most of their admins who have switched to BlueCat.
Key takeawaysThis key takeaway was generated through LLMs crawling the page and coming up with an overview of the content.This article explains five common reasons customers abandon legacy IPAM systems and switch to BlueCat: lack of IPAM adoption, poor visibility and accuracy, slow performance and capacity limits, architectural scalability issues during growth or M&A, and perceived reliability problems. It describes real-world operational impacts such as hours or days lost to manual tracking, inability to answer audit/security questions about historical IP usage, sluggish admin workflows as networks expand, and the strain of accommodating mergers without scalable architecture. The key outcome is that replacing legacy, manual IPAM processes with a reliable, automated IPAM infrastructure improves service reliability, IT efficiency, and the ability to meet always-on business connectivity demands.
Why do some organizations stop using their existing IPAM solutions and revert to spreadsheets or manual tracking?
Organizations often abandon existing IPAM solutions because those systems fail to meet basic usability and reliability needs; as described in the article, administrators end up spending days manually writing and crossing out IPs instead of using the IPAM. Shortcomings can include poor functionality, fragmented data across disparate systems, and an overall lack of trust in the tool. When the IPAM does not deliver accurate, timely data or is difficult to work with, teams default to spreadsheets or ad hoc processes, which further compounds visibility and control problems across the network.
How do visibility and accuracy issues in legacy IPAM systems affect security and operations?
Visibility and accuracy issues undermine both security investigations and routine operations because administrators cannot reliably correlate IP addresses to users or devices. The article gives the example of being unable to answer a security team’s question about who leased an IP during a given time window because the IPAM lacked the necessary historical data. This gap prevents timely incident response, complicates audits, and increases risk. Operationally, incomplete or inaccurate IP records lead to misconfigurations, longer resolution times, and reduced confidence in core DDI services.
What operational problems arise from IPAM systems that are slow or lack architectural scalability?
Slow IPAM systems create inefficient workflows where simple tasks take excessive time, degrading administrator productivity — the article even jokes that clicks take long enough to check sports scores or get coffee. Capacity limits become acute as networks rapidly expand due to natural growth, BYOD, IPv6, and VoIP, causing more admins to manage exponentially more IP addresses. Architectural scalability issues are exacerbated during mergers and acquisitions, where admins face pressure to absorb large address spaces and ask whether they must purchase thousands of additional appliances. Together, slowness and poor scalability impede responsiveness to business change and increase operational overhead.
I’ve seen hundreds of customer architectures and spoken with most of their admins who have switched to BlueCat. A common question I ask is, “Why BlueCat instead of your old system?” There’s always a reason, and often times it’s because their old IP Address Management (IPAM) infrastructure wasn’t performing well.
If I wrote verbatim what those customers told me about their old IPAM systems, this blog entry would be laced with profanity and sarcasm. Keeping it clean, here are the five most common reasons why customers were frustrated with their old IPAM systems.
- 1. Not using IPAM solutions at all They were simply not using their current IPAM solution due to its shortcomings. They were still using spreadsheets and writing stuff down, when they should have been in IPAM. You’d be shocked at how many customers have used disparate systems for tracking the same data in various places. I remember asking a customer why they moved away from their old IPAM solution. The lead admin I was working with wouldn’t tell me. Instead, he showed me: How much time did he have to spend writing out those IPs, doing what he needed to do and then crossing them out? Days.
- 2. Visibility and accuracy Companies didn’t know what was actually going on in your network. Do you ever get asked the question from your security team, “Who leased the IP address xxx.xxx.xx.xxx, on September 20, 2013 from 3:00 AM to 4:00 AM? They were doing something they shouldn’t be.”
- You proceed to check the IP in IPAM and correlate it with a user and device, except the data you’re looking for just isn’t there. Oops.
- 3. It’s SSSLLLOOOOOWWWWW (i.e.: capacity) When you click on something in your IPAM system, do you have enough time to check last night’s sports scores, or even enough time to get another cup of coffee? Tasks should be quick, intuitive and resolve fairly instantly.
- Networks are exploding in size, often doubling or tripling their IP footprint within six to twelve months driven by natural growth, BYOD, IPv6, and VoIP. So what’s the end result? More admins managing more devices and IP addresses.
- 4. Architectural Scalability Mergers and acquisitions drive change in IT. Integrating companies places an immediate short-term burden on systems and infrastructure due to scale. Network Admins are faced with the uncomfortable question: “Do I have to purchase 5,000 new IPAM/DDI-related appliances to accommodate each and every one of the 5-10 M&A’s that I perform each year.” Even without M&A, there are those other “big” projects as mentioned in my third point.
- 5. Reliability DDI infrastructure becomes the technology scapegoat AND people believe it. Can’t connect to an application server by IP? It MUST be a DNS problem! Can’t log in to your workstation? It MUST be a DHCP problem! The printer isn’t working! It MUST be an IPAM problem!
Without an effective IPAM infrastructure your network cannot operate. By replacing your legacy IPAM solutions and manual processes with a reliable and fully automated IPAM infrastructure, you can improve core services reliability, increase IT efficiency and better respond to business demands of always-on application access and business connectivity.
