Ruby on Rails

This is really weird, either a bug (it's 3.1 rc5) or I don't know:

1) DocType.create(:name => request.remote_ip)
DocType.find_by_name('127.0.0.1')
DocType Load (1.4ms) SELECT "doc_types".* FROM "doc_types" WHERE
"doc_types"."name" = '127.0.0.1' LIMIT 1
=> nil

DocType.create(:name => "127.0.0.1")
DocType.find_by_name('127.0.0.1')
DocType Load (1.4ms) SELECT "doc_types".* FROM "doc_types" WHERE
"doc_types"."name" = '127.0.0.1' LIMIT 1
=> #<DocType id: 3, name: "127.0.0.1", description: nil>
