The core message: technologies like Route Origin Validation (ROV) have deliberate, documented scope limitations, and blaming them for not solving problems outside their design goals is like faulting a screwdriver for being a poor hammer. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Route Origin Validation (ROV) actually designed to do and why doesn't it protect against malicious BGP attacks? Route Origin Validation is designed to verify that an AS is authorized to originate a given IP prefix, not to defend against malicious attacks. Its designers deliberately excluded security protections from its scope. Criticizing ROV for failing to block attacks misunderstands its stated goal — it targets accidental misconfigurations, not adversarial behavior. _Network engineers debating ROV's role in their BGP security posture track these distinctions on daily.dev._ ## Similar posts on daily.dev - [A closer look at a BGP anomaly in Venezuela](https://daily.dev/posts/a-closer-look-at-a-bgp-anomaly-in-venezuela-wjsdlj7zk) · Cloudflare · 1 upvotes · 0 comments - [Security validation should begin where attackers begin](https://daily.dev/posts/security-validation-should-begin-where-attackers-begin-o7ec99usa) · CSO Online · 0 upvotes · 0 comments - [Who’s running all those tiny RPKI servers?](https://daily.dev/posts/who-s-running-all-those-tiny-rpki-servers--ota2fdoxt) · Hacker News · 0 upvotes · 0 comments - [Worth Reading: NatJack « ipSpace.net blog](https://daily.dev/posts/worth-reading-natjack-ipspace-net-blog-d5hubg7yu) · ipSpace.net Blog · 0 upvotes · 0 comments - [BGP ORIGIN attribute manipulation and its impact on the Internet](https://daily.dev/posts/bgp-origin-attribute-manipulation-and-its-impact-on-the-internet-fpdysqlcf) · Cloudflare · 2 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#bgp](https://daily.dev/tags/bgp) [View this post on daily.dev](https://daily.dev/posts/worth-reading-misconceptions-about-route-origin-validation-ipspace-net-blog-aune2ja7e) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Worth Reading: Misconceptions about Route Origin Validation « ipSpace.net blog","url":"https://daily.dev/posts/worth-reading-misconceptions-about-route-origin-validation-ipspace-net-blog-aune2ja7e","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/worth-reading-misconceptions-about-route-origin-validation-ipspace-net-blog-aune2ja7e"},"datePublished":"2026-08-11T08:52:10.495Z","dateModified":"2026-08-11T09:00:07.842Z","description":"A pointed commentary referencing Randy Bush's email to the RIPE routing WG mailing list, arguing that criticizing a technology for not providing security when...","image":"https://media.daily.dev/image/upload/s--2-1xRawN--/f_auto/v1722860399/public/Placeholder%2011","thumbnailUrl":"https://media.daily.dev/image/upload/s--2-1xRawN--/f_auto/v1722860399/public/Placeholder%2011","isAccessibleForFree":true,"articleSection":"ipSpace.net Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"ipSpace.net Blog","logo":"https://media.daily.dev/image/upload/s--xS7E82MT--/f_auto,q_auto/v1786438303/logos/ipspace?_a=BAMAMicg0","url":"https://daily.dev/sources/ipspace"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/worth-reading-misconceptions-about-route-origin-validation-ipspace-net-blog-aune2ja7e","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,bgp","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"ipSpace.net Blog","item":"https://daily.dev/sources/ipspace"},{"@type":"ListItem","position":3,"name":"Worth Reading: Misconceptions about Route Origin Validation « ipSpace.net blog"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/worth-reading-misconceptions-about-route-origin-validation-ipspace-net-blog-aune2ja7e#faq","mainEntity":[{"@type":"Question","name":"What is Route Origin Validation (ROV) actually designed to do and why doesn't it protect against malicious BGP attacks?","acceptedAnswer":{"@type":"Answer","text":"Route Origin Validation is designed to verify that an AS is authorized to originate a given IP prefix, not to defend against malicious attacks.
