IONOS (1&1) nameservers

These are the values you would set at your registrar to let IONOS (1&1) run your DNS. Always confirm them in your own account — several providers assign per-account values.

• ns1113.ui-dns.com
• ns1039.ui-dns.de
• ns1069.ui-dns.biz
• ns1102.ui-dns.org

After you save

DNS changes are not instant. Resolvers keep the old answer until the previous record's TTL expires, so a record with a 4-hour TTL can take 4 hours to change everywhere — occasionally longer if an ISP ignores TTLs. Check what the world currently sees before assuming something is broken, and see the troubleshooting page if it still looks wrong after the TTL has passed.
