"Gray" vs "Live" IP - Explanation Request

By Richard S. Murphy ·
I'm probably a little over my head right now but feel certainly someone can help with an explanation.

I am in the process of putting a new server in place and am being asked if I am going to require a "Live IP" or "Gray IP"

I'm far from new to server/workstation work however I must admit that in all my dealings I have not come across this terminology nor do I understand what is truly being asked.

Is there someone that can possibly give me a clear explanation. Following that I would also appreciate any pointers to additional information so that I might have a better understanding.

Thanks.

Richard

Are you implementing a mail server?

It can mean a few things....allocated but not used, or used but filtered (as in a mail server)

This may answer some of your questions:

Yes, a mail server is part of the package.

Dafe2,

The server will have Windows 2003 SBS Standard which includes Exchange along with the other standard fare.

I followed the link you included and while I can understand what in a basic way what they are referring to I'm still unclear as to how it relates to this setup. This server will only be handling mail in the context of retrieving it from the ISP and delivering it to the appropriate user mailbox and, I suppose, sending through the ISP SMTP server.

The supposition here is that the server will act not as a replacement for the ISP but in conjunction with. Does this make sense?

Thanks for the reply.

Hi Richard;

My guess is they're offering the option to filter (mail/SPAM) traffic.

Gray IP's can be used for many reasons. For example we use them to filter known spammers AND other 'Gray IP's for DR testing. If I were you, I'd ask them what THEY offer with each...and you take take the service that best suites your requirements.

Hope this helps

Thanks for the pointers and suggestions. Will definitely take the suggestion about going directly to the ISP for their offerings on Gray vs Live IPs.

Gray code

by Oz_Media In reply to "Gray" vs "Live" IP - Exp ...

The process of converting binary to gray code or vice versa is called gray code conversion, Grey IP conversion is most seen used in low-end VoIP hardware, some 3-Com, Avaya, Cisco etc. accept greyIP, but not usually used for a connection that ALWAYS needs to be open for send and recieve as you would require in a business VoIP networks.

THIS IS TELEOPHONY THOUGH, you are speaking news server so I don't know what exceptions are allowed.

Here's some VERY basic info on gray code.
http://www.nist.gov/dads/HTML/graycode.html

Live IP, would mean a constant connections to the ISP that is LIVE. Often seen in higher end proprietry VoIP systems, NEC PBX etc. (actually they offer a choice)

A cable connection is one form of Live IP as it is always LIVE and connected to the ISP.

A single, direct and always on connection between the server and ISP.

I would see a the differene a applied to a news server would be the grey is more secure but slower than live IP.

An example, I believe HDTV is LiveIP addressed.

Grey IP addressing may not be cost effective though because the service is rather expensive from he ISP. You would have to cotact your ISP for rates and bandwidth charges.

Not a lot of help, I usually don't have to reconfigure the IP's in VoIP systems, most even use DHCP now. But may offer a starting ground for you.

Not really

"THIS IS TELEOPHONY THOUGH"

It's actually quite common in networking of all kinds, usually Mail. The poster said Grey IP not Grey code.

I said THIS IS TELEPHONY THOUGH, to explain that I was referring to Telephony equipment not network architecture.

I also finished that sentence with "...you are speaking news server so I don't know what exceptions are allowed."


Where do you warrant saying;
"Not really
"THIS IS TELEOPHONY THOUGH"

It's actually quite common in networking of all kinds, usually Mail. The poster said Grey IP not Grey code."

How is that NOT really when I have just said my comment applies to telephony?


Grey code onversion is the basis behind GreyIP addresses, as applied to TELEPHONY. Even old POTS systems were based on GreyCode conversion of at the CO.

If someone says they have no idea and what to know what VoIP Banwidth Latency is do you not help them begin underestanding it by telling them what VoIP is or what creates latency?

So again as I explained, "THIS IS TELEPHONY ONLY .....you are speaking news server so I don't know what exceptions are allowed."

Your conlcusive reply was unwarranted, not helpful to myself or the original poster as a result.

Then to top it off, you offer some useful information to the poster on how it MAY apply in this scenario and end with my recommendation to contact the ISP for service details?

So in essence all you did was let him know how it COULD apply to him and spewed at my post?

Having problems today or something?

Your point?

by dafe2 In reply to Try reading it again

The man asked a question I answered it........you suggested it was telephony based on gray code I was trying to be helpful. Also, I knew he was probably doing a mail server or DR setup (but) I asked anyway.

I did not see where talking about other concepts would help (him) in any way.

What's the problem?

obvious, it was only a few lines

by Oz_Media In reply to Your point?

"I'm far from new to server/workstation work however I must admit that in all my dealings I have not come across this terminology nor do I understand what is truly being asked."

Thus I offered some basic info on the "terminology" not the application as you suggest. I also offered some BASIC information on where I had seen it applied.

I then offered some basic information on how it MAY apply in his case followed by your same recommnedation to check the ISP services for more informtation.

This is EXACTLY what the difference between tech Q&A and Dicussions is.

This was an open ended question from someone looking to learn about something, not neccessarily be given a definitive answer.

You keep inferring that I say things I didn't , such as; "You suggested it was telephony based on gray code." No I didn't not in ANY way. I provided a link to grey code conversion, which helps explain the foundations of how greyIP works.

I also explained it was basic, and the example was based on telephony as I had seen it applied. Understanding technology principles is a good starting point to inderstanding technology.

I followed by adding other examples of where I think it is applied.

Your responses are completely knee jerk reactions because you read something into it that wasn't actually there.

In conclusion, we BOTH suggested his ISP would be the best place to see how it applies in their case based on the ISP's offerings and more importantly COST.

So like you said,
"What's the problem?"

Am I misguiding someone by telling him it only applies in telephony? Nope.
Like I said, read it again.
