 # Changelog
 
+## [1.0.0](https://github.com/hertzg/jsr-monorepo/compare/@binstruct/arp-v0.3.0...@binstruct/arp-v1.0.0) (2026-08-17)
+
+
+### ⚠ BREAKING CHANGES
+
+* **@hertzg/ip:** `parseAddress*` return `{ address, zoneId? }` and `parseCidr*` return `Cidr & { zoneId? }` instead of the bare value. `parseAddress` and `parseCidr` take a second `options` argument, so `.map(parseCidr)` becomes `.map((s) => parseCidr(s))`. `expandIpv6` and `compressIpv6` are removed. `parseAddressv6("fe80::1%")`, `"fe80::1%eth0%1"`, `parseCidrv6("fe80::/64%eth0")` and `"fe80::%/64"` now throw; `parseAddressv4("192.168.1.1%eth0")` and `parseCidr("10.0.0.0/255.0.0.0")` now parse.
+* **@hertzg/ip:** every Ip-named export is renamed to its Address counterpart, the ./ip, ./ipv4, ./ipv6 and ./4to6 entrypoints are replaced by ./address, ./addressv4, ./addressv6, and the root parse / stringify / AddressOrCidr are removed.
+
+### Features
+
+* **@hertzg/ip:** layered notation parser with zone IDs and mask dialect ([#295](https://github.com/hertzg/jsr-monorepo/issues/295)) ([dafadec](https://github.com/hertzg/jsr-monorepo/commit/dafadecf397fb527a45a5af22021048b76353e66))

+
+### Bug Fixes
+

 # Changelog
 
+## [5.0.0](https://github.com/hertzg/jsr-monorepo/compare/@hertzg/ip-v4.2.0...@hertzg/ip-v5.0.0) (2026-08-17)
+
+
+### ⚠ BREAKING CHANGES
+
+* **@hertzg/ip:** `parseAddress*` return `{ address, zoneId? }` and `parseCidr*` return `Cidr & { zoneId? }` instead of the bare value. `parseAddress` and `parseCidr` take a second `options` argument, so `.map(parseCidr)` becomes `.map((s) => parseCidr(s))`. `expandIpv6` and `compressIpv6` are removed. `parseAddressv6("fe80::1%")`, `"fe80::1%eth0%1"`, `parseCidrv6("fe80::/64%eth0")` and `"fe80::%/64"` now throw; `parseAddressv4("192.168.1.1%eth0")` and `parseCidr("10.0.0.0/255.0.0.0")` now parse.
+* **@hertzg/ip:** `Cidrv4` and `Cidrv6` are unions; `.prefixLength` is no longer a property of every block, read it with `cidrv4PrefixLength(cidr)` or narrow with `"prefixLength" in cidr`. The universal `cidrContainsCidr`, `cidrOverlaps`, `cidrIntersect` and `cidrSubtract` are overloaded per version instead of generic over one CIDR type.
+* **@hertzg/ip:** every Ip-named export is renamed to its Address counterpart, the ./ip, ./ipv4, ./ipv6 and ./4to6 entrypoints are replaced by ./address, ./addressv4, ./addressv6, and the root parse / stringify / AddressOrCidr are removed.
+* **@hertzg/ip:** parseIpv4, parseIpv6, parseCidrv4 and parseCidrv6 now reject input the RFC grammar does not allow. Sixteen IPv6 forms that previously parsed now throw TypeError, including "1:2:3:4:5:6:7:8::", "0x12::1" and "::1 ". parseIpv6("::-1") returned -1n and now throws. Prefix lengths no longer accept leading zeros. isValidIpv4 and isValidIpv6 return false for all of these.
