Public IP address Natting

As I m aware that 1 public IP address can serve one service port for example HTTPS, i have a upcoming requirement of  more web servers, and i don't have public IP address how i can publish them ? 

• is it the better solution to move to IPv6 on the perimeter firewall with an ISP connection only and the other internal and DMZ connection let it be with IPv4.
• FTD can work in dual mode ip addressing ipv6 and ipv4, do other firewalls ( fortinet and palo alto works in dual mode)  
• Can i Nat IPv6 public ip address to ipv4 address ( web server)
• Also would like to know the public ip range for IPv6
• how Azure and amzaon cloud service provider handle such request hence they have million of web servers hosted online ?

thanks

You need to Look for Virtual hosts 

bb.com. A 192.168.1.100
cc.com. A 192.168.1.100
www.bb.com. CNAME bb.com.
www.cc.com. CNAME cc.com.

And you have to configure virtual hosts for each domain (i assume you are using Apache)
Listen 80

<VirtualHost *:80>
DocumentRoot /www/bb
ServerName www.bb.com
</VirtualHost>

<VirtualHost *:80>
DocumentRoot /www/cc
ServerName www.cc.com
</VirtualHost>

Dear Balaji

can you elaborate more in a layman terms, i couldn't understood your reply, the virtual host solution is from cisco or DNS name resolutions, 

we are not expert like you so bear with us.

thanks

Virtual Host solution from the WebServer Like Apache or IIS server side option.

Cisco router just nat 1 Public IP with 1 Internet IP

Dear Balaji

thanks so IPv6 also work in the same way, but IPv6 are little cheaper in prices and i can get more of them.

before i rate the thread can you answer me the below question 

• is it the better solution to move to IPv6 on the perimeter firewall with an ISP connection only and the other internal and DMZ connection let it be with IPv4.
• FTD can work in dual mode ip addressing ipv6 and ipv4, do other firewalls ( fortinet and palo alto works in dual mode)  
• Can i Nat IPv6 public ip address to ipv4 address ( web server)
• how Azure and amzaon cloud service provider handle such request hence they have million of web servers hosted online

yes you can do IPV6 to IPv4 also or you can use Local IP address  also IPv6 address (like 192 or 10 or 172 address space)
