RADB is still useful in 2026 because it helps make routing policy clearer, more visible, and easier to work with in real operations. That is a good thing. In a networked world that keeps getting more automated, more interconnected, and more dependent on fast troubleshooting, a shared place to document routing intent still has real value. Operators need practical ways to line up prefixes with origin ASNs, support filter generation, smooth out onboarding with peers and upstreams, and reduce the friction that shows up when routing policy is vague or scattered across too many systems. RADB still helps with that. It is not the whole answer to routing security, and it does not need to be. Its value is that it gives serious operators a stable, widely recognized place to publish usable policy data that other networks can actually consume. That makes routing cleaner, troubleshooting faster, and operational trust easier to build. The modern win is not replacing every old tool with a new one. It is combining proven routing-policy visibility with stronger validation so the whole stack works better together.
RADB Still Sits Inside Real BGP Operations
The core of RADB is simple. It is a public Internet Routing Registry operated by Merit Network where operators publish routing objects that describe which prefixes should be originated by which ASNs. In plain English, it is a database for documented routing intent. A route object links a prefix to an origin ASN, and related records add policy and administrative context.
That still matters because the Internet has not fully moved to a pure cryptographic-trust model. Routing policy still gets operationalized through tools, filters, peer checks, and troubleshooting workflows that depend on IRR data being present and sane.
How Operators Actually Use RADB
The first use case is straightforward: publish your route and route6 objects so your announced prefixes line up with your origin ASN in a place other networks can check. That makes your routing intent easier to validate operationally, especially for peers and upstreams that still build filters from IRR sources.
The second use case is automation. Operators use tools such as bgpq4 and IRRToolSet to turn IRR records into prefix-lists, access lists, and policy configuration. Merit explicitly positions RADB around router automation, filter generation, troubleshooting, and network planning. That is why RADB keeps showing up in real workflows instead of just compliance checklists.
What the Real Value Is
The value of RADB is not that it makes the Internet perfect. It does not. The value is that it gives networks a broadly recognized place to publish routing intent in a format other operators still know how to consume. That improves route acceptance, speeds up troubleshooting, and makes peer relationships easier to manage when everyone involved is trying to confirm whether a prefix and origin ASN match expected policy.
There is also a security angle here. Merit explicitly says filtering unauthorized announcements can help reduce route hijacking and denial-of-service risk. Address hygiene is only part of operational trust. Clean routing policy matters too, especially when transferred space, new upstreams, or multi-homed deployments are involved.
RADB Is Not RPKI and That Matters
This is where a lot of explanations go off the rails. RADB and RPKI do different jobs. RADB is an operator-maintained routing-policy registry. RPKI and ROAs provide cryptographic validation of which ASN is authorized to originate a prefix. One documents policy. The other validates origin claims. That is not redundancy. That is complementarity.
In modern operations, the best answer is not choosing one and ignoring the other. The best answer is keeping IRR data and ROAs aligned so your documented routing policy and your cryptographic origin validation are saying the same thing. That gives peers and providers a cleaner basis for trusting your announcements.
Why Enterprise Teams Should Care Too
RADB is not just a carrier issue. Enterprise IT teams using BYOIP, multi-cloud, direct interconnection, or more sophisticated provider relationships also benefit from understanding how routing intent is documented and checked. Even if they never log into RADB directly, they are still affected by whether their providers, transit partners, and network vendors treat IRR data as an operational input.
That is why this subject belongs in supplier conversations too. Prefix strategy is more valuable when the route objects, origin ASN, and security posture are all aligned instead of patched together after a transfer or deployment goes live. Operators that ignore that tend to discover the problem during route acceptance failures instead of during planning.
RADB Is Still Worth Using
The blunt answer is yes, RADB is still worth using. It is not enough by itself, and it should not be treated like a substitute for RPKI. But a lot of the Internet still runs on workflows where IRR data matters, and pretending otherwise is not sophistication. It is negligence dressed up as modernity.
In 2026, RADB is most valuable when it is part of a cleaner routing stack: documented route objects, matching ROAs, sane filter generation, and operators disciplined enough to keep policy current. That is not glamorous. It is just how serious networks stay trustworthy.
