is a free domain research website ( that helps users look up WHOIS, RDAP, and DNS records and track domain names scheduled to expire.

Your domain can do email without a website. MX routes incoming mail; SPF, DKIM and DMARC prove it is really yours. Avoid these mistakes: stale MX records, duplicate SPF, DMARC at p=reject on day one, and expecting instant propagation. https://t.co/R9cKwGzDSR

Apache or Nginx for your small VPS? Nginx's event-driven design leaves more RAM for your app, but Apache wins when your site depends on .htaccess rules. How to choose — and switch without downtime. https://t.co/khmy65nuDp

Your uptime monitor says up but visitors cannot reach your site? The failure may be in DNS, not on your server. Monitor resolution, record answers, delegation, SOA serials, and DNSSEC — from more than one place. https://t.co/86S4hkwuGJ

Got a phishing link impersonating your bank? Report it to Google Safe Browsing to warn visitors, then to the registrar abuse contact to suspend the domain — plus the host and APWG to finish the job. https://t.co/UMkfYYIHyj

Type raspberrypi.local and it just works — no DNS server involved. mDNS multicasts the question to your whole network segment on UDP 5353 and the device answers for itself. Why it stops at VLANs, and how to fix it: https://t.co/lkyjlIQgpJ

VPS or dedicated server? Dedicated is the most powerful hosting you can rent — and the easiest money to waste. Move only on a real signal: CPU over 80%, constant swapping, unexplained slowdowns, or compliance needs. https://t.co/ZlESwQDdX4

Still offering TLS 1.0 or 1.1 on your server? No browser since 2020 needs them — offer TLS 1.2 and 1.3 only, and get TLS 1.3's one-round-trip handshake and mandatory forward secrecy for free. https://t.co/DKTrPT5OvU

The domain you want is taken — buy it at auction. Expiry, drop-catch, and seller auctions each play by different rules, and the winning bid isn't the total: add the renewal fee and check the name's history first. https://t.co/oPLxu7JstA

Moving your domain to a new registrar? You'll need its EPP code — the per-domain secret that proves the transfer is authorized. Where to find it, why it expires after 14 days, and what to do when it's rejected: https://t.co/V0mqbvhDVS

How much does a small website really cost? About $34 a year lean — a $12 domain, a $22 VPS, free SSL — or $72 comfortable. The trap is the renewal price, not the first-year promo. https://t.co/eNHO8tbVbd

Cookies, localStorage, or sessionStorage — which should hold your site's data? Ask: does the server need it, how long should it live, which tabs should see it. Never put a session token in localStorage. https://t.co/pAsjrNcWRX

Type a URL, hit Enter — what happens before the page appears? DNS finds the server, TCP connects, TLS secures it, HTTP fetches the page, and the browser builds it. Each failure points at a different step: https://t.co/pBddOr2GNL

[CC.LA @ccdotla]

Is your DNS traffic hiding stolen data? Tunneling smuggles it out inside ordinary lookups — watch for long random subdomains, thousands of unique names under one parent, and TXT spikes. https://t.co/jGqmBwZt73

Your provider's backup won't save you if the provider fails — a suspended account or dead datacenter takes it with everything else. Keep an off-site copy with rsync to a second VPS or rclone to object storage: https://t.co/ZPSo3uWrlI

[CC.LA @ccdotla]

One VPS not enough? A bigger server is the right first move — but when downtime stops being acceptable, add a second stateless server behind a load balancer. Round robin, least connections, and health checks: https://t.co/csGsShBGbh

[CC.LA @ccdotla]

DV, OV, and EV certificates encrypt traffic identically — the difference is how much identity the CA verified. Most sites should stop at free DV; the browser green bar that justified EV is gone since 2019. https://t.co/Yu31PBI1Iu

Why does a .com WHOIS lookup show so little while a .org shows everything? .com and .net are thin registries — the full record lives with the registrar. Follow the Registrar WHOIS Server field to find it. https://t.co/sVh9UumjqI

[CC.LA @ccdotla]

Your VPS went down and a visitor told you? The monitor can't live on the server it watches — put the checks somewhere else, hosted or self-hosted with Uptime Kuma. https://t.co/ICtJqSEUUO

Can your logo show up next to your emails? BIMI makes it happen — but only with DMARC at enforcement, an SVG Tiny PS logo, and a VMC or CMC for Gmail and Apple Mail. Yahoo needs no certificate. https://t.co/Nco46Jk1i8

Rebranding to a new domain? Map every URL, 301 each page to its match — never all to the homepage — file Change of Address for every variant, and move email first. Keep the old domain renewing. https://t.co/w4W6i7M0Wx
