RDAP Nameserver
The Registration Data Access Protocol (RDAP) is the modern, machine-readable replacement for the old WHOIS service.
An RDAP nameserver resource represents the authoritative information that a Top-Level Domain (TLD) registry publishes about a particular DNS nameserver. By querying this endpoint you can discover, for example, the registrar that manages the server, its associated IP addresses, its status with the registry and any abuse or support contacts.
For details of the protocol and the structure of a nameserver response, see the IETF specification: https://datatracker.ietf.org/doc/html/rfc7483#section-5.5.
Supported Methods
GETLISTSEARCH: Search for the RDAP entry for a nameserver by its full URL e.g. "https://rdap.verisign.com/com/v1/nameserver/NS4.GOOGLE.COM"
Possible Links
dns
A nameserver appears in DNS NS records. Overmind links the RDAP nameserver object to the corresponding dns item so that you can see which zones delegate to this server and whether those zones are also in your inventory.
ip
The RDAP response normally includes the A and/or AAAA records for the nameserver. These addresses are represented as ip items, allowing you to trace from the logical nameserver to the concrete IP resources that sit behind it.
rdap-entity
Each nameserver RDAP document references one or more entities (registrar, registrant, technical contact, abuse contact, etc.). These are captured as separate rdap-entity items and linked so you can quickly identify who is responsible for the server and how to contact them.
