A little insight goes a long way. Find your next good read.
A primary nameserver is the writeable master zone file; a secondary is an automatic read-only replica synced via zone transfer. Both typically answer live traffic simultaneously, not just as passive backup. Domains require at least two nameservers; NameSilo supports up to 13 per domain.
MX priority determines mail server order; lower numbers are tried first. Google Workspace now uses a single record (smtp.google.com, priority 1); other providers like Titan Mail use tiered priorities (10, 20). Never give two different providers the same priority; mail will split unpredictably.
Create a coming soon page in cPanel via Sitepro site builder or manually in File Manager: public_html, create index.html in lowercase, paste basic HTML. Delete existing default index files first. All NameSilo hosting plans include both tools.
Connect custom domain to Adobe Portfolio: add 4 A records in DNS (2 IPs × root and www). Find IPs in Portfolio Settings → Domain Name. Delete conflicting records first. Do not re-enter domain more than 5 times. SSL provisions automatically. 24-48 hours to propagate.
DNS audit checklist: verify A records, audit CNAMEs for dangling records (primary subdomain takeover vector), validate SPF/DKIM/DMARC, check nameserver consistency. Use MXToolbox and SecurityTrails. Remove all records from decommissioned services. Audit quarterly.
Public Wi-Fi captive portals intercept DNS and redirect to a login page. HTTPS blocks this redirect causing SSL errors. Fix: disable VPN and mobile data, visit http://neverssl.com to trigger the portal. Custom DNS like 8.8.8.8 can also block portal detection.
Connect custom domain to Render: A record @ → 216.24.57.1, CNAME www → yourapp.onrender.com. Delete AAAA records first. Render uses IPv4 only. Cloudflare users: use CNAME, set DNS only mode before verification. SSL provisions automatically via Let's Encrypt.
Add rua=mailto:[email protected] to your _dmarc TXT record to receive daily XML aggregate reports. Use a dedicated inbox, not your primary address. Parse reports with Dmarcian or MXToolbox. Start with p=none before enforcing. RUF forensic reports are optional.
clientHold suspends your domain from DNS resolution instantly. Most common cause: missed ICANN verification email (check spam, or resend via Contact Manager). Abuse-related holds: email [email protected] (not live chat). Verify status at namesilo.com/whois.
AAAA records map domains to IPv6 addresses. IPv4 exhausted in 2011; IPv6 eliminates NAT translation overhead. Run dual-stack A and AAAA records simultaneously to serve all clients. At NameSilo: Domain Manager, blue globe, Add New DNS Record, type AAAA. Recommended TTL: 3600.
Fix Deceptive Site Ahead: clean server using backup restore, update all plugins and credentials, then request review in Search Console → Security Issues. Warning disappears within 72 hours if approved. Multiple rejections trigger 30-day Repeat Offender status. Never submit before fully clean.
