Together or separate at a glance
| Question | Domain with your host | Domain at a separate registrar |
|---|---|---|
| Changing hosts | Either keep the domain at the old host after leaving, or transfer it, which is subject to ICANN transfer rules | Point DNS at the new host; no registrar transfer needed |
| Billing | One account and one invoice; SiteGround notes domains still renew separately and are on automatic renewal | Two accounts and two renewal dates to watch |
| Cancellation risk | Cancelling hosting can trigger domain fees; SiteGround says domain fees are not refundable | Hosting cancellation does not touch the domain registration |
| DNS control | Often managed in the host's panel; moving DNS is part of the migration | DNS can stay with the registrar or a DNS provider you choose, independent of hosting |
| Support | One support desk for domain and hosting issues | Two support desks; you coordinate between them |
Registrar transfers are slower and more rule-bound than DNS changes
ICANN's registrant FAQ explains that an Auth-Code is required to move a domain between registrars and that your registrar must provide it within five calendar days of your request. A registrar may deny a transfer within 60 days of initial registration or within 60 days of the last transfer, and must deny it during a 60-day change of registrant lock, which applies after you change the registrant name.
That matters during a host migration. If your domain is with the old host and you want to leave entirely, the registrar transfer is a separate project with its own waiting periods. If your domain is at an independent registrar, a host migration is just new DNS records, and the timing is governed by the record TTL rather than by transfer rules.
ICANN also notes that registrars may not deny a transfer merely because the domain is expired, unless a previous period is unpaid, and that a domain in the Redemption Grace Period must be restored by the current registrar first, which can cost a redemption fee.
Renewal and cancellation traps with bundled domains
SiteGround's knowledge base states that all domain names have to be renewed separately and that all SiteGround services, including domains, are set to automatic renewal billing. Its refund article adds that domain name fees are not refundable and may be due on cancellation even if a promotion initially waived them. In practice, a free first-year domain bundled with hosting may not stay free if you cancel the hosting inside the money-back window.
Before accepting a bundled domain, find the regular renewal price for your extension in the provider's price list and compare it with the registrar you would otherwise use. We could not confirm SiteGround's current .com renewal price from an official page during this review, so check it in the order flow.
Nameserver lock-in can work against you
Some registrars tie the domain to their own DNS. Cloudflare's Registrar FAQ states that all domains on Cloudflare Registrar use Cloudflare nameservers, that those nameservers must remain in place for the domain to be active, and that if you need different nameservers you must transfer the domain to another registrar. Cloudflare says it charges registration, transfer and renewal prices at or below what registries and ICANN charge it.
That is a reasonable trade if you want Cloudflare DNS anyway, but it means you cannot hand DNS to a host that requires you to use its nameservers. If a host's migration guide asks you to change nameservers, check whether it also supports pointing A or CNAME records from external DNS. WP Engine's plan-change article, for example, refers to domains pointed with A records or CNAME records.
Worked example: moving a membership site off a bundled host
A MemberPress site has its domain and hosting at the same shared host and is moving to a managed host. With the domain bundled, the owner has three options: keep paying the old host for the domain only, transfer the domain to an independent registrar before or after the migration, or transfer it to the new host. If the domain was registered or transferred less than 60 days ago, the old registrar may refuse a transfer, so plan the move around that date.
The lower-risk order is to separate the two jobs. First migrate the site by editing DNS records at the current registrar with a lowered TTL. After the new host has run cleanly for a week or two, transfer the domain to the registrar you want, requesting the Auth-Code early since the registrar has up to five calendar days to provide it. Only then cancel the old hosting, after confirming no domain fee will be charged.
Checklists for either setup
- Both setups: record the registrar, the account owner email, the renewal date and the auto-renew setting; enable registrar lock and two-factor sign-in.
- Both setups: export a copy of every DNS record, including MX, SPF, DKIM, DMARC and verification TXT records, before any change.
- Bundled: find the domain's regular renewal price and whether cancelling hosting triggers domain charges.
- Bundled: confirm you can get the Auth-Code yourself and how long the host takes to issue it.
- Separate: confirm which company hosts DNS and that it allows the record types and TTL values your new host requires.
- Separate: if the registrar forces its own nameservers, confirm your host supports pointing records rather than nameservers.
Questions before you decide
Can I move my domain to another registrar right after registering it?
ICANN says a registrar may deny a transfer within 60 days of initial registration or of the last transfer, and must deny it during a 60-day change of registrant lock.
Is a free domain with hosting really free?
Not always. SiteGround says domain name fees are not refundable and may be due on cancellation even if a promotion waived them initially.
