Question 4: Cloudflare Nameservers

Response

Dear Customer,

Cloudflare nameservers are authoritative, offering DDoS protection and security, unlike Google DNS and OpenDNS, which provide recursive resolution for end-user queries without domain control.

Answers

Difference: Cloudflare nameservers manage your domain’s DNS records and add security features, while Google DNS and OpenDNS resolve names to IPs for users without authoritative control.
Delegation with Host DNS: Yes, partial delegation is possible. Use the Cloudflare Dashboard to delegate specific records to Cloudflare while keeping others with your host. Full delegation requires all DNS to use Cloudflare, but you can still reference host IPs in records.

Contact support for assistance with configuration.

Tools I would use:

Cloudflare Dashboard - dash.cloudflare.com for setup.
nslookup/dig - dig NS yourdomain.com to confirm delegation.

Thought Process:

Compared authoritative vs. recursive DNS. Assessed partial/full delegation feasibility.
