Wirewiki - Browse the Internet's Infrastructure as a Graph

TL;DR

TL;DR: Wirewiki turns DNS lookups, propagation checks, zone transfers, and reverse DNS into a browsable graph of internet infrastructure — built by the creator of Nslookup.io after hitting 600k monthly users.

Source and Accuracy Notes

This post is based on Wirewiki’s official documentation at wirewiki.com, the llms.txt reference file, and the Show HN launch post (110 points, February 2026).

What Is Wirewiki?

Wirewiki is a free, open platform for exploring internet infrastructure. Instead of running isolated DNS lookups in separate tools, it interlinks domain names, IP addresses, and DNS servers into a browsable graph — so you can move between related assets without switching tabs.

The project comes from the creator of Nslookup.io, which reached 600k monthly users before the founder hit a ceiling: the domain name locked the product into DNS-only lookups. Wirewiki is the reimagined version — not a collection of standalone tools, but a connected graph of internet infrastructure.

Wirewiki scans the entire IPv4 space for DNS servers and indexes them. It launches with DNS lookup, propagation checking, zone transfer verification, and SPF record validation, with more data sources planned.

What Makes Wirewiki Different

Most DNS tools operate in isolation. You look up a domain, get records, and stop. Wirewiki connects the dots:

• Domain pages show all DNS records for a domain and link directly to the IP addresses, nameservers, and related tools
• IP pages expose reverse DNS, PTR records, and the DNS servers that serve that IP
• DNS server pages list public resolvers Wirewiki monitors across the IPv4 space, organized by country

This graph approach means you can start at a domain, follow a record to an IP, check which nameservers serve it, and see what other domains point there — all without leaving the site.

Core Tools

DNS Lookup

Standard DNS record lookup for any domain. Supports A, AAAA, MX, TXT, NS, CNAME, SOA, and other record types. Results link to related infrastructure pages.

DNS Propagation Checker

Checks whether DNS changes have propagated globally across multiple resolver locations. Useful after deploying DNS changes to confirm they are live worldwide.

DNS Trace

Traces the delegation path from root nameservers down to the authoritative nameservers for a domain. Shows each hop in the resolution chain.

DNS History

Browses historical DNS record changes for a domain. Shows archived snapshots and a timeline of when records changed — useful for debugging DNS issues or investigating domain ownership changes.

Zone Transfer Checker

Tests whether AXFR zone transfer is allowed on a domain’s nameservers. If allowed, displays the full zone contents. This is a security-relevant check — open zone transfers expose your entire DNS structure.

SPF Lookup

Validates SPF records for a domain and expands macros. Helps diagnose email deliverability issues caused by misconfigured SPF policies.

Reverse DNS Lookup

Resolves an IP address back to its PTR hostname. Links to the IP’s full page with additional context.

URL Structure

Wirewiki uses clean, predictable URL patterns:

# Domain hub — all DNS records for a domain
https://www.wirewiki.com/domains/{domain}/dns-records

# DNS propagation for a specific record type
https://www.wirewiki.com/domains/{domain}/dns-propagation/a/

# SPF validation
https://www.wirewiki.com/domains/{domain}/spf

# DNS history timeline
https://www.wirewiki.com/domains/{domain}/dns-history

# IP reverse DNS
https://www.wirewiki.com/ips/{ip}/reverse-dns

# Per-record-type lookup tools
https://www.wirewiki.com/mx-lookup

Deeper Analysis

Why a Graph Instead of Tools?

The founder’s insight is that internet infrastructure is inherently connected. A domain points to IPs, IPs are served by nameservers, nameservers host multiple domains. Traditional DNS tools treat each lookup as an isolated query. Wirewiki models the relationships explicitly.

This matters for debugging. When a domain’s DNS is misconfigured, the root cause often lives several hops away — a stale nameserver record, an IP that changed PTR, a zone transfer that exposes unintended subdomains. A graph view lets you follow the chain instead of manually correlating results from separate tools.

The IPv4 Scan

Wirewiki scans the entire IPv4 address space for DNS servers. This is a significant engineering effort — 4.3 billion addresses to probe. The result is an index of public DNS resolvers organized by country, which powers the propagation checker and adds context to IP pages.

Free and Ad-Free

The founder plans to keep Wirewiki free and open. Monetization, if any, will come from sponsorships and brand integrations from hosting providers, registrars, and CDNs — not display ads. The target audience (developers, sysadmins, security researchers) is exactly the market those companies want to reach.

Practical Evaluation Checklist

• [ ] DNS lookup accuracy — compare results against dig or nslookup for known domains
• [ ] Propagation speed — test after a DNS change to see how quickly Wirewiki detects it
• [ ] Zone transfer security — run against your own domains to verify AXFR is disabled
• [ ] SPF validation — check email-sending domains for policy correctness
• [ ] Graph navigation — start at a domain and follow links to IPs, nameservers, and related domains
• [ ] History depth — check how far back DNS history goes for domains you manage
• [ ] API availability — check if Wirewiki offers programmatic access for automation

Security Notes

• Zone transfer exposure: Wirewiki’s AXFR checker reveals whether your nameservers allow unrestricted zone transfers. If they do, anyone can enumerate all your DNS records — a reconnaissance risk. Fix by restricting AXFR to authorized IPs only.
• DNS history as intelligence: Historical DNS records can reveal past infrastructure, old IP assignments, and previous service providers. This is useful for your own debugging but also available to others researching your domain.
• No account required: Wirewiki works without authentication, which means no query logging tied to your identity. However, standard server-side logging still applies — treat queries as potentially observable by the platform operator.

FAQ

Q: Is Wirewiki free to use? A: Yes. Wirewiki is free and open, with no account required. The founder plans to keep it ad-free and may add sponsorships from hosting providers and registrars in the future.

Q: How does Wirewiki differ from Nslookup.io? A: Nslookup.io focuses on DNS lookups as standalone tools. Wirewiki connects domains, IPs, and DNS servers into a browsable graph, so you can navigate between related infrastructure instead of running isolated queries.

Q: Does Wirewiki scan the entire internet? A: Yes. Wirewiki scans the full IPv4 address space for DNS servers and indexes them. This powers the propagation checker and adds resolver context to IP pages.

Q: Can I use Wirewiki for security auditing? A: The zone transfer checker and SPF validator are directly useful for security audits. Zone transfer results show whether your nameservers expose full zone contents, and SPF validation helps diagnose email deliverability and spoofing risks.

Q: Is there an API or programmatic access? A: Wirewiki’s URL structure is predictable and REST-like, so you can script lookups by hitting the URL patterns directly. Check the official site for any formal API documentation.

Conclusion

Wirewiki takes the scattered world of DNS tools and unifies them into a connected graph. For anyone who regularly debugs DNS issues, audits infrastructure, or investigates domain relationships, it replaces the tab-hopping between dig, propagation checkers, and reverse DNS tools with a single browsable interface. The IPv4-wide DNS server scan adds a data layer that most DNS tools simply do not have.

The project is free, ad-free, and still early — the founder says it is not even at 10 percent of the planned feature set. Worth bookmarking for anyone who works with internet infrastructure.
