Error: connect ETIMEDOUT

Hi, I’m new in ionic
I use Mac OS 10.12.6 (my MacBook pro is “early 2011”)
when I want to setup my project for cordova I used “ionic cordova prepare ios” command on Terminal but I get following error:

Error: connect ETIMEDOUT 10.10.34.35:443

at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1141:16)

would you please help me

That’s not a valid public IP address, so either you have some internal network that is using that 10.10.* network, in which case you need to ask the administrator of said network what 10.10.34.35 is and what’s going on with it, or you have a rogue nameserver that is feeding you bogus DNS information.
