List of IPs for a domain

Question: (How) can I find out a full up to date list of IP addresses for a particular domain?

Detail: I know about ASNs and how they translate to a list of IPs. But for example the published ASNs for Ebay which are here https://bgp.he.net/search?search%5Bsearch%5D=ebay&commit=Search don't provide a comprehensive list. For example I can do an nslookup on ebay and get the first 2 hits of: 66.135.209.52 & 66.211.185.25, neither of which are covered by the ASNs. So I'd really like an up to date list of Ebay's (or anyone's) IPs.

If you're interested, this is for firewall blocking.
