    CO-Hosted

    CoHosted refererer til en situation, hvor flere domænenavne (websteder) bruger den samme IP-adresse til at pege på deres respektive webservere. De kan tilhøre forskellige personer eller organisationer og kan tjene helt forskellige formål. Domænerne, der er hostet på samme IP-adresse som ilemaths.net, er ilemaths.net.

    NS-Gruppe

    En Nameserver-gruppe består af to eller flere navneservere, ofte leveret af webhosting-selskabet eller domæneregistranten. At have flere navneservere tilføjer redundans og forbedrer pålideligheden af DNS-opløsning. Her er domænerne, der bruger følgende navneservere, de samme som ilemaths.net: dns14.ovh.net, ns14.ovh.net.

    RDAP

    RDAP står for Registreringsdata Adgangsprotokol. Det er en protokol, der bruges til at få adgang til og hente registreringsdata for internetressourcer som domænenavne, IP-adresser og autonome systemnumre. RDAP har flere fordele i forhold til WHOIS-protokollen, herunder understøttelse af internationalisering, sikker adgang til data og evnen til at levere differentieret adgang til registreringsdata. Her er de rå RDAP-data for ilemaths.net.
