What is Daum?
Daum's crawler, which collects web documents for Daum web search. Daum says collected documents are not used for anything other than web search.
Crawls pages for a classic search index. Blocking it removes you from that search engine.
Daum also runs Daum-Preview for link previews, which uses the same IP list. The robots.txt token is not case sensitive.
Daum user agent
Kakao documents this user agent for Daum. Version numbers in it change over time, so match on the name, not the whole string.
Mozilla/5.0 (compatible; Daum/4.1; +https://cs.daum.net/faq/service/15/category/4118/detail/28966)Should you block Daum?
Allow it unless you want out of that search engine. Blocking a major search crawler removes your pages from its results.
How to block Daum in robots.txt
Add a group for its token to robots.txt at the root of your site.
A bot follows only the group that names it, so it ignores your User-agent: * rules once it has a group of its own. Repeat any paths you also want kept from it there.
User-agent: Daum
Disallow: /How to verify a request is really Daum
Anyone can send any user agent, so the string alone proves nothing.
Kakao publishes the IP ranges Daum crawls from. A request that claims to be Daum from any other address is not Daum.

Bots don’t run JavaScript analytics, so a script tag never sees them. invisit records crawler reads on the server instead, through its server SDK or a Cloudflare Worker, and shows which bots read which pages, next to your visitors.
