SKY Internet IP Network Request Guidelines


General Criteria

At the request of the InterNIC, The following policies are now in effect:


Fractional Class C's

SKY Internet can assign customers with small networks fractional class C networks. The following are fractional class C's that customers may receive:

    x.x.x.x/25    (subnet mask 255.255.255.128)  126 hosts per subnet
    x.x.x.x/26    (subnet mask 255.255.255.192)   62 hosts per subnet
    x.x.x.x/27    (subnet mask 255.255.255.224)   30 hosts per subnet
    x.x.x.x/28	  (subnet mask 255.255.255.240)   14 hosts per subnet

If you receive a fractional class C network you will need to request in-addr.arpa delegation differently from SKY Internet. For details, see How to Request Fractional In-addr.arpa Delegation from SKY Internet.


SKY Internet's IP networks Are Non-Portable

If you cancel your SKY Internet circuit you may not transfer SKY Internet IP networks to another provider. You will have to renumber your networks into the new provider's address space.


SWIPs (Shared Whois Project)

Internet Service Providers (ISPs) are required to submit SWIPs to the InterNIC for the whole class C's that they assign to their customers. SWIPs are how the whois database is updated at the InterNIC. Once the SWIP is processed a whois query on the IP network will show that the network is assigned to SKY Internet, who assigned it to SKY Internet's customer, who assigned it to their customer, and so on. The InterNIC requires ISP's to submit SWIPs before requesting more IP networks.

This does not mean that the IP networks are permanently assigned to the customer, nor can they take the IP networks with them if they leave the ISP.

In order to submit a SWIP, you have to have a maintainer id. When SKY Internet SWIPs the networks to it's customers that are ISP's the InterNIC will assign them a maintainer id. If you do not know your maintainer id, contact ip-admin@skyinet.net. If you don't have a maintainer id, we'll contact the InterNIC for you and ask them to assign you one.

For details on SWIPs, see How to Submit a SWIP to the InterNIC.


Dialup Terminal Servers

Dialup terminal servers must use dynamic IP address allocation for your dialup customers. Static IP addresses should only be used when there is a technical reason that a dynamic IP address cannot be used. For example, a dialup user that is connected all the time for the purpose of running a web page.


Virtual Web Domains

Virtual web domains are used on web servers that use a separate IP address for each domain name the web server handles. For example, the web server might have the following configuration:

    http://www.company1.com   204.70.1.1
    http://www.company2.com   204.70.1.2
    http://www.company3.com   204.70.1.3
    http://www.company4.com   204.70.1.4

Customers are encouraged not to use virtual web servers, since they waste address space. If possible, use the following alternative format:

    http://www.isp.net/company1   204.70.1.1
    http://www.isp.net/company2   204.70.1.1
    http://www.isp.net/company3   204.70.1.1
    http://www.isp.net/company4   204.70.1.1

As you can see, this scheme allow the web server to serve many URL's on a single IP address. We recognize that companies want their own domain name, but please do your part to minimize your use of virtual web domains to save address space.


Appealing SKY Internet's Decisions

SKY Internet follows the InterNIC guidelines for IP network assignments. If you feel that our decision is unjust, you can appeal directly to the InterNIC. You can either request that we forward your request to the InterNIC for you, or you can appeal to netreg@internic.net. If the InterNIC agrees with the customer request we will assign the IP networks.
