No this doesn't look like any kind of attack. It looks like your computer is trying to use a DNS server that refuses to answer queries, which usually happens if you try to use a DNS server that only answers those coming from a specific IP range. E.g. if you're using a DNS server from an old/different ISP than your current ISP this could happen. Try setting your DNS to 8.8.8.8 to test if it works then.
