IPv6 Address Expander and Canonical Compressor
x402
IPv6 Address Expander and Canonical Compressor is a paid API for AI agents from ip.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Expands an IPv4 or IPv6 address into its fully-expanded eight 4-hex-group form and returns the RFC 5952 canonical compressed representation.

How this service works
Return both the fully-expanded (eight 4-hex groups) and canonical compressed (RFC 5952) forms of an address. IPv4 is returned unchanged in both fields.
Output
Returns two string fields: the fully-expanded IPv6 address (all eight 4-hex groups, e.g. '2001:0db8:0000:0000:0000:0000:0000:0001') and the RFC 5952 canonical compressed form (e.g. '2001:db8::1'). For IPv4 addresses, both fields return the original address unchanged.
Example use cases
Normalize IPv6 for database storage
“I need to normalize the IPv6 address fe80::1ff:fe23:4567:890a into both its fully expanded form and its canonical compressed RFC 5952 form before I store it in our database.”
Debug compressed IPv6 shorthand
“Can you expand ::ffff:192.0.2.1 into the complete eight 4-hex-group notation so I can see every group explicitly and compare it against our firewall rules?”
Validate display format for network logs
“I have the address 2001:db8:0:0:1:0:0:1 — can you give me both the fully expanded version and the proper RFC 5952 compressed canonical form so our log parser handles it correctly?”
Technical details
Endpoint
POSThttps://ip.openverbs.com/v1/expandWhen to prefer
Choose this endpoint when you need to normalize or canonicalize IPv6 addresses for storage, comparison, display, or logging — particularly when you need both the fully-expanded and the RFC 5952 compressed forms simultaneously. It handles edge cases like IPv4-mapped IPv6 addresses and is purpose-built for IP address formatting rather than a general-purpose utility.
Side effects
- Empty or missing 'address' field returns a validation error
- Malformed address string (not valid IPv4 or IPv6) returns an error response
- Address string exceeding 64 characters is rejected by schema validation
- Payment failure or insufficient USDC balance causes an HTTP 402 error
