    A[net/http]
    A --> B{get request RemoteAddress}
    B --> C{is ipv6?}
    C -->|yes| D[render template with IPv6 address]
    C -->|no| E[render template with IPv4 address]
    D --> F{request ipv4 address from ip4.mziesel.nl}
    F -->|success| G[add address to page]
    E --> H{request ipv6 address from ip6.mziesel.nl}
    H -->|success| G[add address to page]
```

works by creating four dns records

```
A		ip.mziesel.nl		<server ipv4>
AAAA	ip.mziesel.nl		<server ipv6>
A		ip4.mziesel.nl		<server ipv4>
AAAA	ip6.mziesel.nl		<server ipv6>
```
