What is .ip6.arpa TLD
The .ip6.arpa TLD is a specialized reverse DNS namespace used to map IPv6 addresses back to hostnames, rather than supporting typical public websites. In practice, this means administrations register and manage .ip6.arpa domains to facilitate DNS lookups for IPv6 resources, while instances of .ip6.arpa websites are rare and largely confined to testing environments. We quantify the current footprint for .ip6.arpa domains with 3 active domains and 0 live websites, reflecting a small, analytical edge case in the global domain landscape. Our ongoing analysis also tracks domains with DNS records 0 and regional adoption signals that are currently 0. Discovered_domain_last_week and 0 in November 2025 provide context for movement in the space. Download the .ip6.arpa domain datasets from webatla.
History and key features of .ip6.arpa TLD
The history of the .ip6.arpa namespace is anchored in IPv6 reverse resolution, where PTR records map address literals back to hostnames within a dedicated DNS ladder rather than to conventional web content. As a data platform, we observe the feature set of .ip6.arpa domains as primarily infrastructural, with most activity limited to DNS maintenance and testing contexts; .ip6.arpa websites, by contrast, remain uncommon operators and are rarely publicly accessible. We quantify the footprint with 3 active domains and 0 live sites, a small sample that informs risk assessment and architectural planning for IPv6 DNS layers. Additional context shows 0 of these entries actually possess DNS records, while regional footprint remains nil in the current dataset across 0 countries. Movement indices read as 0 and 0 in November 2025, signaling minimal movement. Download the .ip6.arpa domain datasets from webatla.
Why and who choose the .ip6.arpa domain
Why and who choose the .ip6.arpa domain: adoption tends to be technical, infrastructural, and governance-driven, with organizations maintaining IPv6 DNS layers rather than pursuing broad public presence; the ecosystem around .ip6.arpa domains and .ip6.arpa websites is primarily infrastructural. In our assessment, 3 active domains underscore a small but persistent footprint, whereas 0 live websites indicate minimal public exposure. The geographic footprint is currently limited, with 0 countries represented in the dataset, reflecting targeted usage rather than mass adoption. DNS readiness indicators show 0 domains with DNS records, pointing to select deployments. Movement signals read as 0 and 0 in November 2025, signaling limited but ongoing activity.
