ISP questions

Building/space already have multiple ISP provisioned.  Fibre and wireless.
Before building a network what information we need to know from ISP before designing and building things out?  Just making sure not missing anything.
I am inheriting an existing space with already provisioned ISP service.
Thanks in advance.

Mostly an ISP just supplies Internet. So for the question above, you need to know from the ISP what speeds they provide, how much data they allow, and at what cost. I am assuming you know that your gear is compatible with their modem (but check) and the ISP should permit you to have their modem in Bridge mode so that you are not hampered for VPN and like uses.

Also know what IP range the ISP is providing and what services/speeds you are paying for.

Got it. So I guess if I find the order details I will have all that info right.

The rising threat of malware-as-a-service is not one to be overlooked. Malware-as-a-service is growing and easily purchased from a full-service cyber-criminal store in a “Virus Depot” fashion. Join us in our upcoming webinar as we discuss how to best defend against these attacks!

You'll see a lot of the information on the bill but not details like the IP range available. you might see a block size but not the details of what IP addresses are allocated.

The Order should have all the details.  Isn't it?
JohnBusiness Consultant (Owner)Commented:
Yes. ISP's normally include all the details when they confirm the order
SeanSystem EngineerCommented:
Usually they don't provide the IP information. Need to call into the ISP or they leave that information when the tech installs the modem. Just depends on the ISP. I would just call and ask. Also make sure you are part of the authorized user list as well as any pin/billing information needed to submit tickets.
JohnBusiness Consultant (Owner)Commented:
My ISP sends all the information but it does depend on the actual ISP.
Bryant SchaperCommented:
Depends on if you ordered static IPs.  The question is lacking, while you say it has ISP service, this does not mean much.  Are you planning on using wireless or fiber?  How are they providing the fiber, I have seen both CAT5/6 handoffs and fiber handoffs.  What kind of equipment are connecting the service too, if you are getting fiber, do you have SFP ports?

Next you will need to know how you are connecting and configuring your device to connect to the ISP, do you need to setup routing protocols, or just get a DHCP address much like DSL.  Typically it has been my experience that when you are getting ethernet/fiber handoffs they are not providing a DHCP address.

You say... Building/space already have multiple ISP provisioned.  Fibre and wireless.

Likely your ISP(s) all provide some type of copper or fiber connection, so unlikely any ISP provides only WiFi.

A big question is why you're using multiple IPs. Likely because you'd like to share traffic between them or you have a slow ISP, you'd like to use as a fallback.

In this case, you'd use a device called a Link Aggregator. Both ISPs will connect to your Link Aggregator, then the rules you define will determine how traffic flows across  your two ISP connections.

Be sure you have a UPS (Uninterruptible Power Supply) powering your incoming ISP hardware + Link Aggregator + WiFi hotspot(s) + extenders. Does no good having redundant ISPs if a brown out or black out or cycle down, takes out your connection.

If this is your first time setting up a system like this, likely best to hire someone to assist you.
Already provisioned? Did the landlord leave that there for your use? If so, then you need to get the IP information from your landlord. You'd also want to know the speeds, and the equipment you need to interface with. And if necessary, logins for equipment you might have reason to access.

If you ordered it, then the information had to have been provided to someone. Otherwise, as already mentioned in earlier comments, you'd have to contact the ISPs.
