Your first BGP session: what to prepare before announcing your own prefix
A practical checklist for your first BGP session: prefix authorisation, IRR and RPKI, upstream details, filters, and how to verify the announcement.
Routing & RPKICan an RPKI-Valid Route Still Be Hijacked? What IPv4 Owners Should Know
Your IPv4 prefix has a valid ROA. Your monitoring dashboard shows RPKI: Valid. Does that mean the route is safe? Not necessarily.
Routing & RPKIRPKI Validation Rollout Plan for Small Networks
RPKI adoption helps small networks improve BGP security by verifying whether route announcements are authorized by resource holders. A structured rollout reduces deployment risks and allows…
Routing & RPKIBGP Communities for Traffic Engineering With IPv4 Prefixes
BGP communities give network teams a controlled way to signal routing intent for IPv4 prefixes. They help steer traffic, mark routes, trigger provider actions, and document policy without…
Routing & RPKIWhat Is a ROA and How Is It Different From an IRR Route Object?
ROAs and IRR route objects both connect an IP prefix with an autonomous system, but they provide different types of routing assurance. Treating them as interchangeable can create problems…
Routing & RPKIROA Expiration Mistakes That Can Break IPv4 Reachability
ROA expiration is a routing risk because many networks now use RPKI data to decide whether an IPv4 route is valid, invalid, or unknown. If the record expires or no longer matches the live…

How reverse DNS works on leased IPv4, who controls the PTR records, and how to set them up and test them for mail servers and API endpoints.
Routing & RPKIMANRS Requirements for IPv4 Network Operators
IPv4 network operators are responsible for maintaining secure routing practices that protect the global internet infrastructure. Routing incidents such as route leaks, incorrect…
Routing & RPKIRoute Filtering Best Practices for Newly Leased IPv4 Space
Newly leased IPv4 space must be announced only after routing authorization, registry records, and peer filters are aligned. If a prefix is visible in BGP before databases and filters are…
Routing & RPKIDetecting Unauthorized Announcements of Your IPv4 Prefixes
Unauthorized IPv4 announcements can move traffic away from the legitimate origin ASN, create outages, expose data paths, or damage address reputation. Detection must combine live BGP…
