# faq
- ? How many .io.vn domains are registered?
- There are 26,610 active .io.vn domains as of October 14, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .io.vn growing or shrinking?
- .io.vn has grown by 224.99% over the last year (+18,422 domains).
- ? Where does the .io.vn domain count come from?
- We ingest ICANN CZDS zone files and Certificate Transparency logs continuously and snapshot the per-TLD count once a day. A .io.vn domain is counted as active if it appeared in a zone file in the last 2 days, or - where no zone file is published - if a certificate was issued for it in the last 12 months.
