InterNIC (SM) Registration Services Frequently Asked Questions
--------------------------------------------------------------
1. Are we in danger of running out of Class B addresses? What can I as a
user do to help?
A Class C number can accommodate up to 255 nodes on a single segment and a
Class B number can have up to 65,535 nodes. Most companies' networks are larger
than a single Class C but much smaller than a Class B. About three years ago,
the Internet community became very concerned about depletion of Class B numbers
and expansion of the upper level routing tables. The response to this concern
is the development of a classless address system called Classless Internet
Domain Routing (CIDR). This method of addressing/routing allows Registration
Services to allocate a block of Class C numbers into customized CIDR blocks.
Each CIDR block is represented as a single set of routes in routing tables.
As a user of Internet address space, you can help by utilizing your address
space efficiently. You should work with the InterNIC or your service provider
when answering estimated growth and network topology questions on the IP
address template. The correct answer to these questions will help determine how
much and what type of address space to allocate.
2. Who should I call to get my address and domain name?
The first thing you should do when connecting to the Internet is select a
service provider. The service provider should help you get IP address space as
well as a domain name.
3. Should I get a Class A, B, or C address?
Your provider will ask questions such as How many nodes do you have now? How
many nodes do you estimate you will have in five years? How many subnets do you
have?, etc. These questions will help determine what kind of IP allocation is
appropriate. For more information, RFC 1466 gives some guidelines about IP
address allocation.
4. I have an individual dialup account. Do I need to have an IP address and
domain name?
If you have a host account, then you do not need an IP address or domain name
since the host already has them. If you are using SLIP or PPP, you will need to
acquire an IP address from your service provider.
5. I want my own domain name. How do I choose a good name? Who do I call to
get this name?
It helps to choose a name already familiar to others, including your customers
and suppliers. You can check to see if your domain name is already taken by
checking with Registration Services. Ask your service provider to help register
a domain name on your behalf.
7. I want to know whether someone has already taken a domain name I am thinking
of using. How do I check this online?
You can gopher to rs.internic.net and select the "InterNIC Registration
Services (NSI)" menu item. Select "Whois Searches" and enter the domain name
you wish to check. If there are entries in the database, they will appear in a
new gopher menu. Browse this menu to check the domain information for any
registerted domains that match your intended entry.
8. When my service provider registers my IP address and domain name, who do
they actually belong to? Do I get to keep them forever?
The addresses and domain names belong to the contacts that are listed on the
applications. Ask your service provider to register your address and your
domain name directly to you, and give your Internet service provider your
organization's full contact information for your domains and addresses.
9. I want to be prepared when I submit an application for a new network
address. What questions will I have to answer? Where do I get these in
advance?
You can receive the network registration template by gophering to
rs.internic.net. Select /InterNIC Registration Services (NSI)/Internet
Registration Archives/templates/internet-number-template.txt. This template
contains the questions you need to answer to register a network.
10. What does InterNIC RS do all day?
We mostly respond to email. :-) The operations staff spends most of their time
responding to registration requests. The engineering staff handles or approves
of registration requests that are exceptional, as well as develops software to
increase efficiency of the registration process.
