What do you do with more than 1 IPv4 and IPv6 in a VPS?

varwww

I have learnt the basics of setting up a VPS, securing it, setting a LAMP stack and installing wordpress. I understand we have to point the ip via an A record to the domain. I also understand that inorder to set up SSL or https, one needs to have an IPv4 but I still have'nt figured out whats the need of more than 1 IP address and what exactly you can do with IPv6 addresses. I read IPv6 is the upgraded version of IPv4 since the internet ran out of addresses. I have a ramnode VPS and they provided 16 IPv6 . What exactly can I do with it? Its been confusing me for a while now.

SSL sites,

Seperate IP for mailserver,

DNS,

Shared Host/Dedicated Site IP's.

I have a vps with a few IPv6 and have no idea what to do with them either. Can they be used the same as IP4 for websites etc?

VPN? Private proxies for various purposes such as crawling? Multiple IP separation for mail server? I think there will be many purposes :-)

How would this be done?

namhuy

Each vhost has its own IP.

So a website can be on a IPv6 just like an IP4

Yes you can do that with ipv4 and/or ipv6 on your server, but most end user ISP don't support ipv6 yet.

I think this site www.sixscape.com is using IPv6 only as I can't access it

I don't have a proper use yet for my 5 IPv6 addresses (on my Iniz VPS). As of now, 4 of them are used on 4 of my websites, with 3 of those websites sharing one IPv4 address (w/ SSL through SNI) and the other one having an IPv4 of its own. All IP addresses have their rDNS set.

So rather than letting your IPv6 addresses rot out, just use them for your websites or for random stuff. As an example, you could set up a mail server with Dovecot using an IPv6 address and Postfix using an IPv4 one. There are so many choices you can make; try some configurations and see which suits your needs the best.

You can run two different webservers on two different IP addresses as they won't conflict.

this is from my windows machine, maybe your network firewall block icmp ping?

What DNS do you use?

Each service on your server should have a separate IPv6
