Frequently Asked Questions
Does this support compressed IPv6 notation?
Yes. Compressed forms using double colon are accepted when they follow valid IPv6 syntax rules.
Can I validate multiple IPv6 values together?
Yes. Paste one address per line and each entry is validated independently.
Does format validity confirm routability?
No. This checks syntax format only, not route reachability or network allocation.
