What Free Tools Does DNForum.com Offer for Domain Investors?

Updated

DNForum.com provides four free, in-house tools for domain investors: an SLD Checker for fast domain availability checks, Deep Whois for researching domain ownership, Bulk NS Search for checking name servers in bulk, and a Live Auction Feed for tracking active auctions across TLDs. These tools are accessible from the site's Tools & Services navigation and are available to registered members of the community, which describes itself as the oldest global domain name community with over 45,000 members.

SLD Checker

The SLD Checker (second-level domain checker) is a fast domain check tool. You enter a domain name, and the tool returns availability information for the second-level portion of the name.

What it's for: Quickly screening candidate domains before committing to a registration or purchase, and running multiple checks without leaving the forum.

How to use it:

  1. Open the SLD Checker from the Tools & Services menu.
  2. Enter the domain you want to check.
  3. Review the returned availability result.

Expected result: A fast pass/fail signal on whether the SLD is available, so you can shortlist names before doing deeper research.

Deep Whois

Deep Whois is the site's domain ownership research tool. Where a standard WHOIS lookup returns registrar and registration data, Deep Whois is positioned for researching domain ownership — useful when you want more context than a single WHOIS record gives you.

What it's for: Investigating who holds a domain, checking registration details, and supporting outreach or acquisition decisions.

How to use it:

  1. Open Deep Whois from the Tools & Services menu.
  2. Enter the domain name you're researching.
  3. Review the ownership and registration information returned.

Expected result: Ownership and registration details you can use to decide whether to pursue a domain, contact its holder, or move on.

Bulk NS Search

Bulk NS Search checks name servers in bulk. Instead of looking up one domain's NS records at a time, you submit a set of domains and get name server data back together.

What it's for: Auditing a portfolio, spotting domains that share name servers (a signal they may share an owner), and verifying that names are pointed where you expect.

How to use it:

  1. Open Bulk NS Search from the Tools & Services menu.
  2. Enter your list of domains.
  3. Run the search and review the name server results.

Expected result: A consolidated view of name servers across many domains, which is far faster than individual lookups when you're working at portfolio scale.

Live Auction Feed

The Live Auction Feed tracks active domain auctions, with separate feeds by extension: .COM, .ORG, .NET, .INFO, .XYZ, .AI, .BIZ, .IO, .CO, and SHORTDOT. There is also an Events Calendar for upcoming industry events.

What it's for: Watching what's currently selling, tracking auctions in the TLDs you care about, and timing bids without manually checking each marketplace.

How to use it:

  1. Open the Live Auction Feed from the Tools & Services menu.
  2. Pick the TLD feed you want (for example, .COM Auctions Now or .AI Auctions Now).
  3. Browse the active listings and follow the ones relevant to your strategy.

Expected result: A running view of live auctions per extension, so you can spot opportunities as they appear rather than after they close.

Practical Notes

  • All four tools sit under the same Tools & Services navigation, alongside the Events Calendar and the DNForum Wiki, so you can move between them in one session.
  • The site also lists a Premium Members Directory and an account upgrade path. The free tools above are separate from that — treat premium membership as a distinct offering rather than a requirement for the tools described here.
  • Registration is free and the community is built around buying, selling, and discussing domains, so the tools are designed to feed into forum activity (marketplace threads, appraisals, and discussion) rather than stand alone.

If your goal is quick availability screening, start with the SLD Checker. If you're evaluating a specific name you might acquire, pair Deep Whois with Bulk NS Search to understand both ownership and infrastructure. If you're hunting for inventory, go straight to the Live Auction Feed for your target TLDs.
