Network tools
Two kinds of network tools live here. Offline tools (record analyzer, subnet calculator) run entirely in your browser. Online lookups send only the domain you type to the public resolver you choose, and only when you press Look up.
DNS LookupOnlineLook up A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records over DNS-over-HTTPS using Cloudflare or Google Public DNS, and compare both answers.NS LookupOnlineFind the nameservers (NS records) for a domain over DNS-over-HTTPS, see the zone’s SOA and resolve each nameserver’s IPv4 and IPv6 addresses.Offline DNS Record AnalyzerLocalPaste zone-file or dig records and get offline checks for duplicates, CNAME conflicts, TTLs, SPF syntax and lookup count, DMARC tags, MX and CAA records.Subnet / CIDR CalculatorLocalCalculate network address, broadcast, netmask, wildcard, usable host range and count for IPv4 CIDR, split subnets, and expand or compress IPv6 prefixes offline.

A latency/jitter test, DNS propagation checker and full internet speed test need dedicated measurement infrastructure, provider permission and honest methods. They will only appear once they can measure what they claim.
