Bring-Your-Own-IPs and ASN

Introduction

In November 2019, RIPE, the organization that manages IP allocations allocated the last /22 IPv4 block, which means that they have run out of IP addresses. This has caused a global increase in IP address prices and restrictions on IP assignments, including here at NovoServe.
Therefore we encourage our larger customers to get their own IP blocks, which will give them more flexibility and freedom. These blocks can be leased through so-called IP brokers or Local Internet Registries (LIRs).

In order to keep networks separate and dedicated to specific customers or purposes, we also encourage larger customers to apply for their own Autonomous System Numbers (ASNs). In fact, this is a new requirement for our resellers, as stated in our Reseller document here: https://www.novoserve.com/industries#resellers

 

What is an AS Number?

“An Autonomous System (AS) is a group of IP networks run by one or more network operators with a single, clearly defined routing policy. When exchanging exterior routing information, each AS is identified by a unique number: the Autonomous System Number (ASN). An AS is also sometimes referred to as a routing domain. Current RIPE Policy requires a network to be multi-homed, and have a unique routing policy for an ASN to be assigned. Requests must show the routing policy of the AS. Any organisation can acquire an ASN. This requires a contractual agreement with a sponsoring LIR or with the RIPE NCC.”

How does it work?

Using your own ASN we are able to announce your own blocks under your ASN, completely separate from our network. Besides the technical advantages, this also brings some level of white labeling to your services. NovoServe will provide your network with transit through our massive backbone. On the other side you will need to take into consideration that you will be responsible for your own abuse policy, so you will need to manage it by yourself. Then we have simple examples like DNS, which is required if you want to set up reverse PTR records for your IPs.

 

How to get my own ASN and IP block?

Internet resources like an ASN and IP blocks are obtained through an official sponsoring LIR or by becoming a member of the RIPE NCC. Getting such objects requires some basic paperwork in order to validate your request. You can find more RIPE-related info on the Autonomous System (AS) Number Assignment Policies page here: https://www.ripe.net/publications/docs/ripe-679

In order to apply for an ASN, you will usually need to follow the following steps:

  1. Find a sponsoring LIR or broker; you can find the official list here: https://www.ripe.net/participate/member-support/list-of-members
  2. Provide all requested documentation and information.
  3. Ask the NovoServe networking team for information regarding the multihomed requirement from RIPE; we will provide you with two of our ASNs.
  4. After successful allocation from RIPE, ensure that you have properly created route objects and ROAs (for RPKI) for your ranges. Both are mandatory.
  5. Then contact NovoServe to arrange our BGP session/announcement, provide us your ASN and IP block (you will need a /24 or larger). If you have obtained your IP blocks through a third party, please also provide us a LoA (Letter of Authorization).
  6. Our network team will set up a virtual router instance.
  7. Your ranges will start to work under your ASN. It may take some time before this is fully propagated on the internet.
  8. You can now use your IP addresses with our dedicated servers.
