While on my home wifi I checked the domain name for my iPhone using Airport Utility, the domain name utopia.net is indicated. Same for my iPad. When I look at the domain name that comes up for my Mac, it's a Comcast name as it should be. Can anyone shed any light on this? Thanks.
domain name is passed by DHCP along with IP and gateway, dns info. Something in your network has been hacked.

Re: DPC3941T Modem hacked? Utopia.net
utopia.net is part of a DNS hijacking attack. You should check all of your systems for malware, and then make sure your devices are getting their DNS servers from us automatically or set them manually:
IPv4:
75.75.75.75
75.75.76.76
IPv6:
2001:558:feed::1
2001:558:feed::2
Is your Mac for example plugged into a comcast router.. whereas the iphone and ipad are using wifi from a different source. Tell us all the equipment you have on network.. what modem and what router. What model is the airport you are using? And you should be able to see what domains they are using. Talk to comcast because this virus is apparently affecting your router.

Utopia.net is a known indicator of a DNS Hijacking. Not sure why at this point it is only affecting your iOS devices. This has been an issue with Comcast service.
Please take a look at the following article:

Thanks!
What is utopia.net?
