SWIP (the Shared WhoIs Project) is the process where Class-C
assignments appear in InterNic's whois database.
Xodiax will participle in the Shared WhoIs Project (SWIP) and will
ASSIGN or ALLOCATE IP netblocks equal to or shorter than a /29
to our end customers. This is done in accordance to the Internet
Engineering and Task Force (IETF) RFC 2050 http://www.ietf.org/rfc/rfc2050.txt.
The determining factor of whether to ASSIGN or ALLOCATE IP netblocks
to the end customer is based upon the business model of the customer.
If the customer provides Internet access (e.g. dial-up modems,
DSL, cable modems), then the Xodiax IP netblock will be ALLOCATED
to the end customer. If the customer provides content (e.g. ASPs,
Web hosting, Email services), the Xodiax IP netblock will be ASSIGNED
to the end customer.
If a customer has been ALLOCATED an IP netblock from Xodiax, it
is expected to see them SWIP any of their customer IP assignments
before requesting more IP space from Xodiax.
The purpose of using SWIP:
- To accurately keep track of assigned IP space.
- To expedite new CIDR requests from ARIN.
- To allow the Internet-public to contact the correct netblock
holder(s).
- To point in-addr.arpa requests to customer equipment rather
than Xodiax’s DNS servers.
Definitions:
- ARIN: American Registry of Internet Numbers. IP address assignment
in North America. ( http://www.arin.net)
- Netblock: A block of IP addresses
- ASSIGN: To give IP addresses to end customers. The customer
is not allowed to further SWIP the IP addresses to their end
customers.
- ALLOCATE: To give IP addresses to end customers. The customer
is allowed to further SWIP the IP addresses to their end customers
The Importance of SWIP
Xodiax supports and enforces InterNic's SWIP policy which is stated
at ftp://rs.internic.net/policy/internic-ip-1.txt
Below is an excerpt of part of that document which states, in
part:
Subsequent allocations of CIDR block addresses will be based on
need; this need will be demonstrated based on the number of assignment
actions that have been transmitted to the InterNic Registry. Assignment
information is to be forwarded to the InterNic within 7 days of
the assignment so that the "whois" may be maintained
efficiently. Transmission of assignment information is also necessary
for the following reasons:
a) To ensure that a provider has exhausted, or is about to exhaust
its current CIDR allocation such that an additional allocation
is justified.
b) To allow operational people to see which organization is using
the assigned address space and whom to contact in the event of
operational/security problems, etc.
c) To assist in the IP allocation studies.
Assignment actions can be submitted by utilizing the database exchange
format defined by the SWIP project. Information regarding SWIP
may be obtained via anonymous FTP from rs.internic.net. The files
may be found under the /pub/swip directory.
ALL ISP's, regardless of where they receive their CIDR blocks should
either SWIP the assignment information or establish an RWHOIS server.
If SWIP is the chosen method, ISP's should register with the InterNic
as an ISP to receive a maintainer ID necessary to SWIP the assignment
information.
Briefly stated: this means that if Xodiax customers do not SWIP,
it could hamper Xodiax's ability to obtain more Class-C address
space for it's customers. Every customer with a full /24 IP address
space is required to SWIP.
Help with SWIP
The information below is not a replacement for the InterNic's SWIP
documentation, but only a supplement. You should still read that
information before proceeding with your SWIP process.
Here's an example of a properly completed SWIP template for an
example customer who is using SWIP to ASSIGNing space to one of
his customers:
WDB_version: 1.4

--------------------------------------------------------------------------------
(N)ew assignment: If this Class-C address space
is currently un-SWIPped.
(M)odify Assignment: If the information on the current
SWIP is no longer accurate and you want to correct it, choose the
(M)odify option.
(D)elete Assignment: If the information on the current
SWIP is no longer accurate and the Class-C space is no longer used,
you will want to choose the (D)elete option.
(A)llocate: (A)llocation is an assignment that can
be reassigned to other customers. (If your customer has customers of
his own, space should be Allocated.)
A(S)sign: A(S)signed space stays with the person it's
assigned to.
ntsnum: This is the lowest address in the Class-C
assigned-block.
ntenum: This is the highest address in the block.
ntname: SDF-10-10-220: Create a unique name for the
address space. Only use letters, numerals, or dashes. Do not use domain
names, as periods are not acceptable characters.
org: The Company Name
street, city, state and zipcode:
The Company Address
cntry: The 3-letter code for where the company is
located.
maint: The maintainer ID. (A full list of maintainer
IDs is available at ftp://rs.internic.net/
pub/swip/maintainer.list.
If you don't have a maintainer ID, email hostmaster@internic.net
and ask for one.
Leave the following spaces blank. Nameservers responsible for reverse
mapping have already been established.
hname:
ipaddr:
hname:
ipaddr:
nichandl: Put the NIC handle of the company's technical contact
here ("XODI"
for Xodiax). Skip the rest of the template.
Do not put END OF FILE after each template in a submission, but
only after the last template. You can mail any number of templates
to reassign@internic.net in one message. Separate templates with
the CUT HERE line.
