PChome and Net-Chinese (網路中文) are common domain registrars in Taiwan. At both, handing your DNS to another provider is called 「DNS 自管」 (self-managed DNS). This guide covers each one's official steps for switching to C Building's nameservers. Both sites are in Chinese, so menu names are quoted as they appear.
The steps follow PChome's self-managed DNS FAQ and Net-Chinese's DNS host settings FAQ, checked on October 15, 2026.
Step 1: start hosting in C Building first
Order matters: finish the setup in C Building first, then change the nameservers at PChome or Net-Chinese. If you change the nameservers first, your old records stop working at once, and your website and email can go down.
- On the website's "Domains & publishing" page, or the "Domain" tab in the editor settings panel, find "Let C Building manage your DNS" and click "Let C Building manage DNS".
- Choose how to read your current records: "Detect automatically", "Import from Cloudflare" or "Paste a zone file".
- Under "Confirm the records to bring over", tick each record you want, use "Add a record" for any that are missing, then click "Start hosting".
- The screen shows "Last step: change the nameservers at your registrar" with four nameservers and a "Copy all" button.
C Building's four nameservers are ns1.cbuilding.net, ns2.cbuilding.net, ns3.cbuilding.net and ns4.cbuilding.net. After you start hosting, change the nameservers within 3 days. If you don't, this setup and the records you brought over are deleted, and you have to click "Start again". The full flow is in Let C Building manage your DNS.
How the two differ
| PChome | Net-Chinese | |
|---|---|---|
| Where | 管理我的網址 → 〔進入〕 → DNS自管 | 域名管理 → domain → DNS → DNS主機設定 → DNS自管 |
| Count in the docs | Example shows two; no maximum stated | At least two |
| IP address | Can stay empty when the nameservers aren't under your own domain | The FAQ asks for host name and IP |
| Timing in the docs | 24 to 48 hours | 12 to 24 hours for DNS record changes |
PChome
PChome's domain service now lives at myname.pchomebiz.com.tw. The homepage menu item 「設定DNS自管 / 代管」 leads to this setting.
- Sign in to 「管理我的網址」 (manage my domains).
- Click 〔進入〕 (enter) to the right of the domain, then choose 「DNS自管」.
- Enter ns1.cbuilding.net, ns2.cbuilding.net, ns3.cbuilding.net and ns4.cbuilding.net.
- IP address: PChome says that if the DNS servers are not under your own domain, the IP field can stay empty. C Building's nameservers are under cbuilding.net, so leave it empty.
- How many: the official example shows two and doesn't state a maximum. Enter all four; if only two fit, use ns1 and ns2.
- Timing: PChome says to allow 24 to 48 hours after you save.
- If you used PChome's free DNS hosting, its records stop applying once you switch, so bring them into C Building first.
Net-Chinese
- Sign in to your Net-Chinese account.
- Go to 「域名管理」 (domain management) → your domain → 「DNS」 → 「DNS主機設定」 (DNS host settings) → 「DNS自管」.
- Enter at least two nameservers (all four is better) with host name and IP address, then save.
Net-Chinese asks for both host name and IP address. C Building's screens don't show IPs. The table below is what public DNS returned on October 15, 2026. If the form needs an IP, the IPv4 column is enough.
| Nameserver | IPv4 | IPv6 |
|---|---|---|
| ns1.cbuilding.net | 205.251.196.82 | 2600:9000:5304:5200::1 |
| ns2.cbuilding.net | 205.251.193.12 | 2600:9000:5301:c00::1 |
| ns3.cbuilding.net | 205.251.194.225 | 2600:9000:5302:e100::1 |
| ns4.cbuilding.net | 205.251.198.20 | 2600:9000:5306:1400::1 |
- Once you switch, records can no longer be managed at Net-Chinese; you edit them in C Building.
- Net-Chinese's default hosting uses ens1/ens2.net-chinese.com.tw (cns1/cns2 for .tw) and allows up to 50 records for free. Bring the records you need into C Building before you switch.
- Net-Chinese says record changes take 12 to 24 hours. It doesn't state a separate time for nameserver changes.
- Net-Chinese support: (02) 2531-9696, [email protected], weekdays 08:30–19:00.
How long does it take, and how do I check?
Each registrar's own timing is in the table above. C Building says it usually takes minutes to hours, and can take up to 48 hours. Once it takes effect, your website connects automatically.
- When you're done at the registrar, go back to C Building and click "Check now".
- When it says "The nameservers have changed. Your DNS is now managed by C Building.", you're done. Use "Manage DNS records" to edit records from then on.
- If it says "The nameservers have not changed yet.", it also lists the nameservers the registry has on file, so you can spot a typo.
- Filling in only some of the nameservers still works, but all four is more reliable.
If the nameservers are later changed away from C Building, record editing is paused. If they are not changed back within 14 days, hosting ends automatically. Before you switch, also read Before you change nameservers: email and DNSSEC.
