cidr-calculator

CIDR / subnet calculator: network and broadcast address, first and last usable host, netmask and wildcard mask, total and usable address counts for any IPv4 CIDR block. Network planning and validation. $0.01 per calculation.

Cloud / hosting provider detection for an IP or hostname: AWS, Google Cloud, Azure, Cloudflare, DigitalOcean, Hetzner, OVH, Akamai/Linode, Fastly, Oracle, Alibaba, Vultr, Fly.io, Render and others, from the announcing ASN, plus a CDN flag. Where is this service hosted? $0.01 per lookup.

cloud-provider-detect

ipv6-expand-compress

IPv6 normalizer: expand any IPv6 address to its full 8-group form and back to the canonical compressed form (RFC 5952), with type classification (global unicast, link-local, unique local, loopback, multicast, IPv4-mapped). Deduplicate and compare addresses reliably. $0.01 per address.

ip-country

IP to country: the country an IPv4 address is registered to, from the regional internet registry (via Team Cymru and RDAP), with ASN context. Honest about what it is: registry data, not precise geolocation, and free of any keyed geo-IP database. $0.01 per IP.

Check whether an IPv4 address belongs to a CIDR block. Give '<ip> in <cidr>' (or comma separated). Firewall rule validation, allowlist checks and log filtering. $0.01 per check.

ip-in-cidr-check

IP address intelligence in one call: reverse DNS hostname, ASN number and owner name, announced prefix, country and regional registry from Team Cymru, RDAP network name and organization, private/bogon classification and cloud provider detection (AWS, Google, Azure, Cloudflare...). Log enrichment, abuse triage and infrastructure mapping. $0.01 per IP.

ip-address-info

ipv6-support-check

IPv6 readiness check for a domain: AAAA records for the site, IPv6 on its mail exchangers and on its nameservers, and whether it is dual-stack. Compliance and modernization audits. $0.01 per domain.

cdn-ip-check

Is this IP a CDN or reverse proxy? Detects Cloudflare, Akamai, Fastly, CloudFront, Imperva/Incapsula, Sucuri, StackPath, Bunny, KeyCDN, Gcore and others from the announcing network, so you know whether an address is the origin server or an edge. $0.01 per lookup.

tor-exit-check

Tor exit node check: whether an IPv4 address is a current Tor exit, from the Tor Project's published exit list (cached one hour). Fraud screening, abuse triage and access policy decisions. $0.01 per IP.

is-ip-alibaba

Common ports scan: TCP-connects to 12 well-known ports (FTP 21, SSH 22, SMTP 25, HTTP 80, HTTPS 443, MySQL 3306, Postgres 5432, Redis 6379, 8080, 8443, Elasticsearch 9200, MongoDB 27017) and reports which are open. Quick exposure check for a host you operate. Cloudflare-fronted hosts cannot be probed. $0.01 per host.

common-ports-scan

IP address classification: is it a valid IPv4, and is it public or private/RFC1918, loopback, link-local, CGNAT shared space, multicast, documentation or reserved (bogon)? Input validation and log filtering. $0.01 per IP.

ip-private-bogon-check

range-to-cidr

IP range to CIDR converter: turns any IPv4 start-end range into the minimal list of CIDR blocks that cover it exactly, with the address count. Firewall and allowlist preparation. $0.01 per range.

is-ip-in-bell-canada-70-24

IP WHOIS via RDAP: the registered netblock for an address with its name, handle, allocation type, country, start and end addresses and the owning organization, from the authoritative regional registry. Ownership research and abuse contacts. $0.01 per IP.

ip-whois-rdap

subnet-split

Subnet splitter: divide an IPv4 CIDR block into equal subnets of a smaller prefix (e.g. a /22 into /24s), listing up to 256 resulting networks with counts. VPC and VLAN planning. $0.01 per split.

ipv6-prefix-64

IP address validator: tells you whether a string is a valid IPv4 or IPv6 address, which version, the normalized form and its classification (public, private, loopback, link-local, multicast...). Input validation for forms, logs and APIs. $0.01 per check.
