Weird DHCP behavior from MN-700

I've set my MN-700 DHCP to use a pool from 10.10.10.100 up to 10.10.10.253.
But for some reason, the first time I got an IP asigned it was 10.10.10.144.
After a power cycle I got an IP of 10.10.10.45 which is outside the pool I
have defined.
Is anyone knows why it is doing so? And why does it seem to just go in a
random fashion instead of starting with the first available one?

One sugestion I have for MS developers: Adding a fixed lease based on MAC
address would be very usefull. This way we don't have to use a fixe IP for
port fowarding. The reason I don't wanna use a fixed IP is that I need it to
be dynamic so I can use it at the office and at some Internet Coffee.

THat is normal for the IP to be randomly selected from the pool of IP
addresses.

I guess it is normal when it is by design. But it's not the case for all
other DHCP server. On NT4, the DHCP assign it in a logical order.
And I doubt it is normal for the DHCP server to asign IP outside of its
pool.
Is it a know bug?
Thanks for your reply

Which version of the firmware are you running on the MN-700?

Some of the earlier versions had some DHCP problems.

Dear Maxx,

No, its not a "bug" or "known issue"...unless you're
consider the whole oragnization of the Internet a
mistake. It is the IANA standard for Class A IP
assignments. Not all IP classes are the same. For
example, the (192.168.2.*) private IP series that is the
default in the MN-700 is Class C. Here,the first 3
octets are the Net ID, with only the last octect being
the Host ID. In Class A IPs, only the first octet is the
Net ID, while the remaining 3 octets are all Host IDs.
So, in your case, only the first (10.*.*.*) sets the Net
ID. All else is upto the DHCP server. You should be
happy you're getting (10.10.10.*).

Lastly, I think basing fixed connections on physical
address alone instead of IP could be a security issue.
MAC addressing can be easily "spoofed". Since people
would not easily or routinely change their MAC address,
once the enter a WiFi zone, it would be recorded and
could be copied. Just my thought.

Hope this helps!

I am now in the office and can't tell the version number. But unless MS
release a new one recently, my MN-700 came with the latest firmware out of
the box.
Thanks

What I meant was for the problem I have, been asigned an IP that is not
included in the defined pool. About my comment on IP been given in a random
manner within a defined pool, I was just saying that not all DHCP servers
are behaving this way. And I gave NT4 as an exemple. I still don't

Yes. But having the possibility to do it for say, one MAC to always be given
10.10.10.100 seems to me pretty safe and convinient. BTW, my previous
Linksys router was able to do it.

Cool. What I'm trying to say is the DHCP server-
assignable pool of possible IPs for Class A IPs
(10.*.*.*) is the last THREE octets. For Class C it is
only the last (192.168.2.*). The subnet, in other words,
can be described within three octets for Class A, but
only one octet for Class C.

This is a little confusing, since in theory you can use
(192.168.1.*) to (192.168.255.*) in Class C. But once
you assign the first three octets, the DHCP server-
assignable IPs (the range of IPs) are limtied to the last
octet (256 possible IPs). Class C IPs are also known
as "16-bit" addresses. Class A are known as "24-bit"
addresses. You can guess what Class B private IPs
(172.100.*.*) are called.

Just try to add a little understnad; background to IANA
standards :)

The class of an IP address is determined by the first octet.

10.*.*.* is a class A IP address with a default subnet of 255.0.0.0, but
the MN-100, MN-500, & MN-700 always have a subnet mask of 255.255.255.0
which is now suppernetting the Class A IP address to only have 254 IP
addresses, instead of the 16,777,214 possible for a non-suppernetted
Class A IP address.

It may be a problem with the fact that you chose a class A IP address

Here is some more information on suppernetting that I got from when Ii
was trained to support the MN-100 & MN-500.

(2^n) - 2 = number of hosts or subnets (where n is in the number of bits
remaining or stolen)

As I mentioned it is the first octet that determines the class. I have
the classes ranges in decimal for easy reading for those who don't know
binary which is how an IP Address is read.

Class A = 1-127 (default subnet = 255. 0 . 0 . 0 ) addresses =
16,777,214 (127 is reserved for the loopback)
Class B = 128-191 (default subnet = 255.255. 0 . 0 ) addresses = 65,534
Class C = 192-223 (default subnet = 255.255.255. 0 ) addresses = 254

Ken you forget the a network & node can not be all zeros or all ones.
That is why the equation of (2^n) - 2 = number of hosts or subnets
(where n is in the number of bits remaining or stolen) should be used.
Thus making a 255.255.255.0 subnet only have 254 possible nodes.

for example we take the following decimal information and convert it to
binary so that a computer understands it.

===============================================================

All the numbers in Decimal format.

IP = 192.168. 2 .9
subnet = 255.255.255.0

===============================================================

All the numbers in Binary format.

IP = 11000000.10101000.00000010.00001001
subnet = 11111111.11111111.11111111.00000000

===============================================================

This means that "11000000.10101000.00000010" is the network & "00001001"
is the node on that network.

Once again a network & also a Node can not be all zeros or all ones.

Another example this time a Class A Address with the default subnet.

===============================================================

All the numbers in Decimal format.

IP = 10.0.10.9
subnet = 255.0.0.0

===============================================================

All the numbers in Binary format.

IP = 00001010.00000000.00001010.00001001
subnet = 11111111.00000000.00000000.00000000

===============================================================

This means that "00001010" is the network & "00000000.00001010.00001001"
is the node on that network.

Once again a network & also a Node can not be all zeros or all ones.

That was a load of good information! Thanks for taking time to detail it all
out in plain english :D

I think that you only learn when I'm in a good mood. Sometimes I say
RTFM or tell you should have done a google search. This was a bit to
complicated to put in the manual or find with a quick search on google
because you wouldn't know what to search for.

It shouldn't assign an IP outside the lease range...

On the other issue, it does associate IP's to MAC
addresses but only for the duration of the lease (even if
the PC is disconnected in between). If you set the lease
to the maximum 2 weeks, you'll get the same IP address
assigned provided you reconnect the PC before the lease
time expires and the router is not rebooted meanwhile
(powered off).

Another thing, is that for certain servers (but not all)
you can do with an app-triggered port forwarding. In my
case, it works fine for the Apache web server.

Ditto on the "outside the defined pool" problem; mine does the same ...
assigns addresses past the last address I told it to, 192.168.2.99.
