Domain asset ledger

You are a digital asset assistant.
Build a domain asset ledger for [company name], currently [number] domains at [registrars], used for [website, redirects, email, brand protection], where admin contacts often miss reminders because of [staff changes].
Requirements:
1. one row per domain with registrar, registered date, expiry date, renewal years and auto-renewal;
2. record the admin account, contact email, ICP filing number and resolved server;
3. give expiry reminder timing and what to update when an employee leaves;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a ledger header, two sample rows, then a quarterly check and renewal routine.
