[ESET Smart Security firewall add domain and spacebar after popup ask]

Hi, first my english not very well and i want to ask 2 questions

 

Windows 7

ESET Smart Security 10

 

question 1:

how can i input domain instead of IP to firewall zone ?

 

i set the 3 major Win7 program allow access to internet

svchost.exe/wuauserv (Windows Update) port: TCP 80, 443

svchost.exe/NlaSvc (detect internet for switch Home / Public network function) port: TCP 80

svchost.exe/CryptSvc (is about update the .cab files ...etc) port: TCP 80

 

so i go to Firewall > Zone > created a zone called Microsoft Trusted Zone, and input all the IPs is collected by popup ask Allow or Deny windows

104.116.243.17,
134.170.165.248,
134.170.165.249,
134.170.51.190,
173.223.85.3,
184.28.37.50,
184.84.60.29,
191.232.80.58-191.232.80.60,
191.234.72.186,
203.186.47.187-203.186.47.240,
203.80.97.8-203.80.97.27,
207.46.154.200,
207.46.155.185,
216.58.197.110,
216.58.199.110,
23.2.16.208,
23.218.34.222,
61.244.242.24-61.244.242.32,
65.55.138.112-65.55.138.114,
65.55.163.222,
65.55.252.71,
96.7.54.104

 

and then i go to Firewall > Firewall Rule > set the 3 major Win7 program allow access to zone: Microsoft Trusted Zone

so now i just need to add or remove IP from Microsoft Trusted Zone, and no need change the 3 major program firewall rule anymore

but actually all the IPs is ref to the domain as below

deploy.akamaitechnologies.com

ds.download.windowsupdate.com

fe2.update.microsoft.com

www.microsoft.com

crl.microsoft.com

 

so can i add the 5 domain to zone ?, instead of keeping mark down the IP from popup window and add to Microsoft Trusted Zone

 

 

question 2:

the popup window asking a program Allow or Deny to access internet, but i am typing a document and press a spacebar,

and the popup window gone, so this action will make to default Allow or Deny ?

if default is Allow access internet, i think this is the security problem

 

so can i change the popup window default select Deny ?

or the popup window ignore all the keyboard input ?

 

sorry my english not very good, Thankyou
