in the table 'Historical classful network architecture' the 'leading bits' part would look better in a format: 0??????? (and this is wrong: 000????? <-- add this as a comment to the table because after I've first) 10?????? (and this is wrong: 100????? read the article, I've made this mistake before reading the) 110????? table. I've made a mistake because of the misleading description above the table (first 3 leading bits). First 3 leading bits != not always 3 of them (sometimes one). More than that, I'd add something like: so the number (for the A class network) looked like: 0+ {0; 127}. There were 128 networks available within the class. For B class: 128+{0;63} , for C class 192+{0;31}. See this article source code as I don't know how wikipedia formats text.

As i see, there is not any ip showing sites like : http://www.ip-goster.net/ e.t.c. in external links.

Did you decided not to put this kind of sites in Ip Adress page ? ıf it isn't there is a lot of sites like that in multi language. I think it would be helpful to viewing users. —Preceding unsigned comment added by 212.175.20.11 (talk • contribs) 14:55, August 31, 2007

Perhaps www.geoiptool.com can be mentioned ?

Maybe https://www.whatismyip.com/ can be added? — Preceding unsigned comment added by 64.128.27.82 (talk) 21:34, 3 August 2012 (UTC)[reply]

Ownership, Value and Trading

I suggest that it would be useful to add information about ownership on public ranges. Once a range has been allocated out, is that range 'owned' by that organisation it is allocated to, or is it 'lent'. Some address space is now traded on closed markets (e.g. Addrex, so addresses have value. It is suggested that ARIN/RIPE have no legal hold over addresses given our prior to their advent.

With the IPV4 ranges quickly being used-up (another topic, probably not for here) more and more cases of IP-selling, value, cost and legal ownership/rights are going to arise globally in the next few years (my subjective view only). — Preceding unsigned comment added by 62.23.212.216 (talk) 12:40, 21 August 2012 (UTC)[reply]

Interfaces have IP addresses not devices

The opening sentence is conceptually wrong. Interfaces have IP addresses not devices. This is obvious in two common situations: laptops with both an Ethernet interface and a wireless interface and a router which has a WAN interface and a LAN interface.

<add.> I tend to agree, and interfaces aren't a subset of device, as devices themselevs can be logical rather than physical. ie an interface doesn't haev to be associated to a particualr physical device.
