Usar ListDomains com o AWS SDK ou a CLI

    /// <summary>
    /// List the domains for the account.
    /// </summary>
    /// <returns>A collection of domain summary records.</returns>
    public async Task<List<DomainSummary>> ListDomains()
    {
        var results = new List<DomainSummary>();
        var paginateDomains = _amazonRoute53Domains.Paginators.ListDomains(
            new ListDomainsRequest());

        // Get the entire list using the paginator.
        await foreach (var domain in paginateDomains.Domains)
        {
            results.Add(domain);
        }
        return results;
    }

Para listar os domínios que estão registrados na conta atual da AWS

O comando list-domains lista informações resumidas sobre as os domínios que estão registrados na conta atual da AWS.

Esse comando só pode ser executado na região us-east-1. Se sua região padrão estiver definida como us-east-1, você poderá omitir o parâmetro region.

aws route53domains list-domains
    --region us-east-1
