IPv4 leasing & IPv6 penetration into networks

IPv4 leasing offer from broker but uses gmail address.

Got an email at my LONAP address yesterday asking if we had any spare blocks available for IPv4 leasing. I used to occasionally get them when at Timico as I think did most of the industry. This time it’s prompted me to look a little deeper into the issue. After all it is over 3 years since the exhaustion of the IANA IPv4 address space – you may remember the Move over IPv4 Bring on IPv6 party which was a huge success even if I say so myself.

I looked at the google keyword stats for “IPv4 leasing”. The UK averages only 10 searches a month for this term. Doesn’t really smack of an industry getting desperate. The “brokers” of IPv4 addresses do appear to exist in somewhat of a twilight zone. For example the email I got was from an Adam Green with an address of [email protected]. If he was kosher he would use a proper business address. It isn’t a kosher business model anyway.

These guys swipe email databases from the likes of RIPE. The one I got didn’t address me by name which in the gmail world normally leads to automatic spam labelling. In November we have RIPE69 coming to London and I’ll be looking for guest posts on the subject of IPv6. The subject of IPv4 leasing will almost certainly come up at the meeting although to be honest people should be focussing on moving their infrastructure on to IPv6, something that still isn’t particularly mainstream.

It would be interesting to hear from anyone with an IPv4 address space problem although I doubt anyone would put their hand up to admit it.

Taking a look at some LONAP stats, out of 152 connected networks 113 or 74% of them have registered IPv6 blocks with the IXP.  At the LONAP AGM we ran a little exercise with prizes for those who registered using an IPv6 address. Of the 50 or so attendees and excluding LONAP staff we had 8 people register using an IPv6 address. Suggests that use of IPv6 is still somewhat limited even amongst the network engineering community you would think would be early adopters.

Taking the exercise a little further we looked at the websites of LONAP members. Of the 149 checked 74 of them have no IPv6 enabled site. If you have no idea what I’m talking about with IPv6 this info will be of no interest whatsoever. However those in the game should find the stats v interesting and probably not a surprise.

That’s all for now. Stay tuned for more IPv6 stuff as it hits my screen…
