hosts

[Vegan]

I wonder if there is a problem with my hosts file:

127.0.0.1 localhost
127.0.1.1 contract-developer.dyndns.biz ubuntu
64.59.160.13 nsc1.cv.gv.shawcable.net
64.59.160.15 nsc2.cv.gv.shawcable.net

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

A couple of entries don't look familiar, but...
what is causing your concern?
