ipv6

Validate that a string is a valid IPv6 address. Accepts full and compressed forms.

Signature​

NguardValidators.String.ipv6: ValidatorFn

A parameterless validator — used directly without invocation.

Reactive forms​

import { FormControl } from '@angular/forms';
import { NguardValidators } from 'ng-nguard';

const address = new FormControl('', [NguardValidators.String.ipv6]);

Template-driven forms​

<input ngModel name="address" nguardIpv6 />

Error key​

{ ipv6: true }

Notes​

  • Accepts:
    • Full form (2001:0db8:85a3:0000:0000:8a2e:0370:7334)
    • Compressed form (2001:db8::1)
    • Loopback (::1)
    • Unspecified (::)
  • IPv4-mapped IPv6 (::ffff:192.0.2.1) is not supported by the bundled regex.
  • IPv4 addresses fail — use ipv4 or ip for those.
  • Empty strings fail.
