Protocol and service context
This catalog provides a browser-friendly reference for protocols and ports so users can interpret service labels and transport mappings without leaving the site.
Reference Catalog
Browse the ports catalog directly in the website.
This page embeds the monthly ports catalog directly in HTML and keeps the browser experience searchable and paged without requiring a separate raw JSON action.
Return to the GeoIP downloads hub, browse the CIDR reference and root zone database, or review the monthly reference publication methodology.
Useful for rules and troubleshooting
The embedded format is practical when checking firewall rules, application ports, or network service conventions while reviewing operational data.
Related GeoIP paths
Use the GeoIP database overview for the product view, or the downloads hub for release-based file access.
Browse and filter
Use the search field to filter the embedded catalog client-side. The browser view remains paged, with an upper page-size option of 10,000 rows for materially larger future catalogs.
The embedded ports catalog is ready.
