DNS fail

I saw this host in a traceroute and had to be sure:
> server jupiter.is.co.za
Default server: jupiter.is.co.za
[snip]

> set type=ptr
> 218.115.209.168.in-addr.arpa
[snip]

218.115.209.168.in-addr.arpa name = mail.amorphous.net.

> set type=a
> mail.amorphous.net
[snip]

Name: mail.amorphous.net
Address: 196.211.13.115
168.209.115.218 != 196.211.13.115

It looks like Internet Solutions forgot some old reverse DNS records when updating things, and re-used the address for infrastructure.
