I just noticed today that domain foo.bar resolves to 127.0.53.53 (http://foo.bar, http://whois.domaintools.com/foo.bar)
In my case this ends up on the localhost Apache, but I wonder why the registrant did not simply chose to point to 127.0.0.1? Is there any specific reason?

127.0. 53.53 is a special IP addresses that is used by ICANN to prevent DNS name collisions with the new gTLDs. In your case the . bar gTLD was delegated in February.
The Internet Assigned Numbers Authority (IANA) is responsible for the overall coordination and management of the Domain Name System (DNS), and especially the delegation of portions of the name space called top-level domains. Most of these top-level domains are two-letter country codes taken from the ISO standard 3166.
ICANN is the global non-profit organization responsible for coordinating the Internet's core systems of unique identifiers, most notably the Domain Name System (DNS).
DNS servers convert URLs and domain names into IP addresses that computers can understand and use. They translate what a user types into a browser into something the machine can use to find a webpage.
127.0.53.53 is a special IP addresses that is used by ICANN to prevent DNS name collisions with the new gTLDs.
In your case the .bar gTLD was delegated in February. So the 127.0.53.53 is a big hint for people using .bar in their internal setups that the .bar domain name will be used in the global DNS very soon.
If you look closer at the foo.bar record you see more information:
