And what are their major assets and immediate needs?
And how do you assess their regional connectivity?
And how do you monitor routes, world-wide?
And how do you counter route leaks or hijacking attacks?
At Leitwert, we conduct large-scale measurements from vantage points all around the globe. Our field-tested routing analytics provides the answers you seek.
Buy Raw Data
We offer plans for accessing raw path measurement data. Our rich routing data originates from active network probing on a continuous basis and is post-processed with scientifically backed up algorithms. If you have an integrated solution that lacks detailed routing insights, have a look at our customizable API solutions. Get in touch with us and request a sample of our rich data sets or ask for a free trial account to put our query API to the test. We will certainly provide you with a unique perspective into your networks.
With Leitwert tools, you have access to versatile routing analytics. Our products are steered by a powerful cloud analysis engine and offer intuitive, Web-based visualization frameworks. Beside manifold results from control plane (BGP) and forwarding plane (IP) measurements, we also incorporate various meta data such as the geographic location of Internet participants.
Monitor the Internet ecosystem
Observe new peering and transit links, analyze market trends, and filter your results by ISP, geography, and physical connection type.
Engage in peering reconnaissance
Study arbitrary ISPs, assess their strengths and weaknesses, visualize customer cones and transit routes, and identify competitive peer routes.
Attract more customers and traffic
List potential customers, prepare marketing arguments based on routing facts, and study the routing history of your prospects.
Identify valuable peering partners
Search for mutuallly beneficial peers, anticipate routing changes, and evaluate potential performance gains as well as their risks.
Assess IXP locations
Evaluate the benefits of public peering, list available ASes at IXPs, and identify suitable interconnect sites to setup new POPs.
Choose transit providers that fit your individual needs, reduce upstream costs, rate your peers by various metrics, and identify adverse routing agreements.
Assess routing anomalies
Study connectivity loss, identify routing loops, assess the impact of route leaks and identify originating and amplifying ISPs.
Detect hijacking attacks
Register networks for close monitoring, receive real-time alerts for hijacking and man-in-the-middle attacks, and evaluate countermeasures to mitigate ongoing events.
Build up your own situation room
Consolidate routing alerts, define responsive actions and escalation strategies, assemble tailored reports, visualize historical routing changes, and conduct forensic analyses.
Visualize IP-level topologies
Check the internal routing of peers and upstreams, evaluate load balancing, and identify bottlenecks and single points of failure.
Monitor your services
Rank IP links by latency, debug performance issues, trace MPLS tunnels, and visualize paths filtered by source, destination, and transit ISPs.

In order to provide you with rich routing data, we carry out large-scale network measurements on a periodic basis. Although we attach great importance to non-invasive probing, you might have felt disturbed by our measurements. Contact us and we will gladly cooperate with you to resolve any issues at hand. In the meantime, we encourage you to take a closer look at our measurement approach.
Traceroute — Our Approach
We randomly select measurement targets for each routed IP network by utilizing a combined view of more than a hundred BGP routing tables. After removing destinations that are listed on our well-maintained blacklist, we distribute the resulting targets to our world-wide network of dedicated servers. We then perform IP-based path measurements to all selected destinations by sending TCP packets to port 80. Note that we do not send or request any application data. In any case, we gracefully close connections with a TCP RST.
We are doing no harm!
Research and Development
We are closely tied to internationally renowned universities and commit ourselves to constantly advance the state-of-the-art on network measurements and analysis. Beside publishing in academic journals, we consider it our scientific responsibility to share our research with the public. On this page, we will regularly post updates on new measurement techniques and innovative evaluation algorithms, and we will thoroughly discuss our practical findings. You may also check out the news archive for a list of all previous articles.
New website design
Today, we launched our re-engineered website. Beside a fresh design, we significantly optimized responsiveness and page loading times. State-of-the-art web programming now offers new interactive features throughout all of our pages. Feel free to explore!
Reliable Assessment of BGP Hijacking Attacks
Our paper has been accepted for publication by the IEEE Journal on Selected Areas in Communications. With this work, we developed the Hijacking Event Analysis Program (HEAP), a novel approach to assess the legitimacy of BGP hijacking alarms in real-time.
