What's new

This page is where new tools, guides, and fixes get announced from now on, newest first. The homepage also shows the latest few entries so returning visitors can see what changed without hunting for it.

dig +dnssec is now available — it adds RRSIG records and the ad (authenticated data) flag to a response, so you can see whether a domain is signed and whether a resolver actually validated it. Combine it with +short in either order.

New guide: Checking DNSSEC with dig +dnssec — how to read a signed answer, confirm a domain is signed at all, and diagnose the most common DNSSEC failure ("unreachable, but only from validating resolvers").

Most real troubleshooting doesn't start with a single command — it starts with a symptom. Four new guides in Commands walk through the actual sequence of tools you'd reach for:

• Website is down — dig → nc → curl → openssl s_client
• Email isn't arriving — dig → whois → nc
• SSL certificate errors — dig → nc → openssl s_client
• Slow or unreachable server — dig → ping → mtr → nc

Every command in each guide is one you can run directly in the terminal as you read.

Three additions for anyone who registers an account:

• Privacy Policy — exactly what's collected (a hashed IP, not the raw address; account email/username if you register), why, and for how long each piece is kept.
• Terms of Service — acceptable use and rate limits, written to be actually read rather than skimmed past.
• Account page — see your username, log out, or delete your account and its data at any time.

• Accounts — sign up with email and password, or sign in with GitHub or Google. An account is still entirely optional: the terminal works the same anonymously, an account just carries a higher rate limit and something to come back to.
• Mobile terminal — touch scrolling, a fullscreen mode, and a layout that no longer breaks on a narrow screen.
