<p class=MsoNormal>While cleaning up some old DNS records (again) I took a look
at some of our old address space. 2 x /23s from 2 providers. I did a
quick whois and both are still pointing to us. One we have not used since early
2001 the other since late 2004. I did some tests and one of them still routes
to the last hop before it hit us.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Then I took a look at the records for a client with a /22
that we managed the DNS for. I don’t know how long he has not had the IP
space but it’s been at least 3 years and more likely closer to or over 4 years.
Still pointing to him (and his company no longer even exists) and still routing
to the last hop before him. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>How much space is out there and routed and going no place?
Is there any way to find out? It’s more of a question to satisfy my curiosity
but I think it would be interesting to know.<o:p></o:p></p>
