I can't visit websites that have “.dev” domain

Ok, I figured it out:

1. I used command scutil --dns which returned current resolvers configuration
2. There was entry:

 resolver #8
  domain   : dev
  nameserver[0] : 127.0.0.1
  flags    : Request A records, Request AAAA records
  reach    : 0x00030002 (Reachable,Local Address,Directly Reachable Address)

3. Then I went to the catalog /etc/resolver and I found there file called dev.
4. I've removed that file and everything started working just fine
