IP 0.0.0.0/0
Hi Any useful link that explains this IP address range in details, please? Thanks in advance!

Urrr -- 0.0.0.0/0 is the *entire* IPv4 address range, and 0.0.0.0/32 is just the single IPv4 address 0.0.0.0. For any given network, the lowest address in the network is reserved. Historically, the lowest address was one of the two allowed choices for the broadcast address; later, the broadcast a...

hi all, i have 2 drawings - ground floor and first floor. when i do an ID on a point on the grid i get the same readings for both drawings however, when i xref one into the other or both into a new drawing they come in in different locations. i've checked they're both using world UCS and the same units. any ideas? i thought with autocad 0,0 was always 0,0? cheers rob "Coro, Rob" <RE-Coro@bdp.co.uk> schrieb: >hi all, > >i have 2 drawings - ground floor and first floor. when i do an ID on a >point on the grid i get the same readings for both drawings however, >when i xref one into the other or both into a new drawing they come in >in different locations. i've checked they're both using world UCS and >the same units. any ideas? i thought with autocad 0,0 was always 0,0?

Hi, shouldn't > (= 0/0 0/0) => NIL or > (= 0/0 0/0) => T instead of giving out division by zero? 0/0 is different from 1/0, which is the non-existent number n such that 1 x n = 0. The actual result of that expression depends of what you think 0/0 is. I personally feel that 0/0 is any number n such that 0 x n = 0, that is all numbers. hal9@cyberspace.org (Hal Niner) writes: > Hi, > > shouldn't > > > (= 0/0 0/0) => NIL > > or > > > (= 0/0 0/0) => T > > instead of giving out division by zero? 0/0 is different fro...

0.0**0 = ?
I'm wondering if 0.0**0 (as opposed to 0.0**0.0) has the value 1 as per fortran standard or if this is left to the compiler vendors (different vendors do different things, unhappily).

Simplifying {0,0,0}.X.{0,0,0}
Hello, In brief: Is there a way that I can specify that "X" is a matrix and will resolve to zero when dot multiplied with a vector of zeros? I'm constructing a swathe of expressions that contain things like (when expanded): {0,0,0}.X.{0,0,0}, where X is an arbitrary (well, positive definite) square matrix of obvious size, and I'd like to be able to have mathematica simplify that for me without much intervention. My only option at the moment is to manually perform the replacements {{0, 0, 0}.X._ -> 0, _.X.{0, 0, 0} -> 0} (the left and right vectors won...

Laptop configuration: 1. obtain an IP address automatically 2. obtain DNS Server address automatically I ran "ipconfig", other computers says IP:192.168.1.1** and mask: 255.255.255.0.

Portably replacing -0.0 with 0.0
So my program has the following function at the moment to replace -0.0 with +0.0 in a function argument: static inline double sign_flat(double v) { if (v == 0.0) return 0.0; return v; } But when compiling with the Intel Compiler icc at optimization level -O2 or higher the above still produces -0.0. This raises two questions: 1. is the compiler free to convert above function into a NOP? 2. does anyone know a work-around or even more suitable formulation to achieve the same? Preferably not some integer operations using signbit since our main system is a Power6 which has some issues with FPU depending on ALU results and vice versa. I've done some searching but the Internet is flooded with people trying to wrap their head around the fact that -0.0 exists. 1. is actually the less interesting question since even when the answer was no I still want my code to work with the Intel compiler.

route 0.0.0.0 twice
Hi, I some doubts question regarding a Cisco config. In the config I can see the following two lines: ip route 0.0.0.0 0.0.0.0 192.168.1.1 ip route 0.0.0.0 0.0.0.0 192.168.1.2 I know that these addresses are active in two interfaces. We had a 2Mbit connection that was upgraded to 4 Mbit. Our ISP told us to add the routes and that with those two routes we would be able to use the two links as one. Is this true with Cisco's CEF? My question is: 1. what's the route selected by the packets? Thanks, NC Nuno Cristelo wrote: > Hi, > > I some doubts question regarding a C...

dhclient leasing 0.0.0.0

Since my rc.firewall script automatically finds the ipaddress i will have to restart the firewall as well. Does someone have a clue how to persuade dhclient to find the right ip-address at bootup?

ARP requests for IP address 0.0.0.0
Hi, we are facing strange behaviour on our small network with a system sending out ARP requests now and then asking to resolve the IP address 0.0.0.0. According to the first three bytes of the MAC address (00-14-51) it is an Apple machine. Does anyone have an explanation for this behaviour?

Yes. The address "0.0.0.0" is the "any" address. That means, "any" host should answer that request. The MAC address you're seeing is some random MAC address from your network (most likely).

Had a look at the logs again and the ARP requests comes from 0.0.0.0 and a valid destinatin IP which I think is the IP of the host sending the request out.

IP 0.0.0.0 blocked, explanation please
First, if this is really basic stuff... I've got NIS 2003 on Win XP Pro. Standalone home computer connecting to Internet thru 512k ADSL. My firewall logs show quite a few entries every day re outbound TCP from local address 0.0.0.0 blocked by implicit rule. I'm not familiar with use of IP 0.0.0.0. Are there any valid reasons I should permit access from IP 0.0.0.0 ? Approx half of the 20 or so daily entries are to remote IP 129.237.35.42:80 which is Kansas University re Lifemapper software I'm running. This is a valid application but I don't know enough to say if it's been misprogrammed/misconfigured. I could permit by adding 129.237.35.42 to Trusted Sites but is this wise ? Any advice on 0.0.0.0 welcome. thnx Geoff Think Default gateway: In firewall it can substitute for a specific interface when installing policy to more than one enforcement point/node at the same time. The destination address 0.0.0.0 indicates the default destination, if no other specific routes are configured for the given packet destination. This default destination is where all packets will be sent, and it is assumed that this destination is capable of forwarding these packets to the ultimate destination, or to another router along the appropriate path.
