Assign AS number

Autonomous System Number

The NAV telecommunication company is an official member of the RIPE NCC International Registry being authorized to allocate AS numbers.

AS Number
(Autonomous System Number)

An Autonomous System consists of a group of networks that use Internet Protocol, a group that is maintained by one or more network operators with a single, clearly defined routing policy. Upon exchanging external routing information, each AS is identified by a unique number: Autonomous System Number (ASN).

Assign IP addresses (if you have not already assigned).


The Autonomous System Number (AS) is allocated to customers who want to perform dynamic routing and traffic balancing using the BGP protocol.

Mandatory requirements

For an AS allocation, you need to have at least two Internet access links through two different providers and have at least a 256 IP addresses CIDR (/24).

Possible conditions imposed by providers

Each provider may have their own policy and conditions. In this regard, please, before requesting an AS number, verify these conditions with your internet service providers.

For IPv4 and IPv6 allocation please access the page

IP Allocation

Terms and conditions

Payment for AS number allocation

- The IP Allocation fee is paid only once, it represents the cost of a service and includes the annual fee only if the allocation is made after the first 6 months of the current year.

- The annual fee represents the maintenance cost. Invoicing for the annual fee will take place in the first month of each calendar year.

- Prices are expressed in EURO, do not include VAT and are calculated at the B.N.R. exchange rate from the billing day.

- The IP allocation term is up to 24 hours after payment receipt.

Maintaining and ownership of the AS number

After you have paid the invoice for the AS number allocation and after its actual allocation, you will be the owner of the right of use and you can dispose as you wish by the AS number. Please note that the AS will remain allocated to your company only as long as you meet the requirements of NCC RIPE and pay the annual fee to the LIR (ro.nav or ro.server).

Rules for allocating and maintaining IP addresses and AS numbers.

1. Introduction

IP addresses (IPv4 / IPv6) and provider numbers (AS) are limited resources, which determines certain allocation conditions imposed by the regional registry (RIR) and not least by the local registry (LIR).
Obtaining resources (IP and AS) is done in some cases with both the approval of the LIR (ro.nav) and the approval of the RIR.
The notion of "class C" has disappeared, in the current context the CIDR notation will be used, "/24".

2. Definitions

Public IP addresses are divided into 2 categories, in terms of allocation:
[ PI ] - are spaces allocated by RIPE.
- The applicant must have at least 2 Internet connections
(Different ISPs with different ASs).
- For these spaces, you must own/request
an AS, indispensable for dynamic routing via BGP.

[ PA ] - are spaces allocated by NAV Communications.
- It does not matter the number of Internet connections.
- You do not need to own/request your own AS number,
because they can aggregate on the AS of your ISP.
- If you have your own AS, they can be aggregated and routed dynamically.
- In general, they can also react to the AS's of the providers to whom
you will later connect to, or even your own proprietary AS.
( The exception is RCS-RDS, for which addresses
are changed free of charge when you sign in or opt-out of their services. )

[ IPv6 PI Addresses ] are spaces (>=/48), allocated to clients holding an AS number and at least 2 Internet connections (different providers, each provider holding its own AS number).
[ AS Number ] is allocated to customers who want to make dynamic routing and have at least one block /24 (256 IP addresses), with the possibility of aggregating to that size.
For AS allocation, peering agreement with at least 2 partners is required.

3. General conditions for IP address allocation

For allocation of IP addresses, a global coverage of at least 50% in the first month, 60% in 2 months, and 80% in 3 months.
Individually on subnets, the values of 40% of the first month, 60% in 2 months, and 80% in 3 months are accepted, and the overall use rate.
Address coverage is done by counting the addresses used by equipment, vhosts, .... and customers ( attention to the fact that a client can get maximum 1 IP / link / host )
We draw attention to the fact that these thresholds are minimal.
Customers requesting PI IP addresses must have the peering agreement of two providers that have different ASs.

4. General conditions for the allocation of AS numbers

Owning the peering agreement of two providers with different ASs and a block /24 are minimum conditions for obtaining an AS.

5. Rights, obligations and terms of use

The client must provide both the LIR (ro.nav) and the RIR with documents demonstrating the need to obtain Internet resources if they are expressly requested.
These documents include: company documents, identity card of the requestor, invoices/receipts on equipment, IP address charts, logs, customer name lists, contracts with their clients, contracts with their suppliers, network schemes, flyers and price lists.
These documents will be either scanned by email (recommended) or by fax, to the LIR or to the RIR, as the case may be.
Documents may be requested both during and after assignment, please note that these documents are required purely informationally to determine whether the minimum conditions are met and their confidentiality is guaranteed.
After obtaining the resources and paying the value of the services, the client will be provided with the resources for use, the delivery of manuals/links, and not requiring training from LIR (ro.nav).
For resources that will still be managed by the LIR, from the point of view of the update of the information (generally PA addresses), the LIR will update any information without incurring additional fees, which are included in the annual fee.
Cases of transfer of the right of use (owner change) is charged with 25% of the registration fee (minimum 50 Euro + VAT).
Resources are not assigned "for life", the client has the obligation to return these resources if they do not use them or the initial conditions are no longer met.
PA addresses are returned within 30 days of the notice of termination of the contract between the LIR and the client/end-user.
Non-use of resources (IPs, ASs) over a period of more than one month (30 days) may result in the withdrawal of allocated resources.
The attempt to sell, sell or lease the resources obtained to a third party (by exceeding a maximum of 8 IPs/client) entails the cancellation of allocated resources.
Using resources for purposes that are in violation of Romanian laws or to perform "SPAM" actions, hosting those who "SPAM" automatically leads to the cancellation of approval for all the resources obtained.
The LIR may cancel the allocated resources if there are suspicions of illegal activities (SPAM and not only) or at the request of the RIR without prior notice to the client.
Failure to provide documents requested by LIR/RIR within a maximum of 2 weeks automatically entails the cancellation of approvals for that client.
The blocking of IP addresses or AS by anti-SPAM organizations or other providers does not oblige the LIR or RIR to change addresses.
The LIR will advise the client of the possibilities and will try to solve the problems with it.

6. Payment of services

The allocation fee is a fee based on the service provided and not by the number of resources obtained (eg for IPs).
The maintenance fee for PI/PA IPs and AS will be paid annually to the LIR, its value is set by the LIR and may change over time without prior notice to the client.
The transfer fee (ownership change) is 25% of the allocation fee in effect at the time of the transfer, the LIR providing a new service ("of transfer").
Non-payment of fees gives the LIR the right to take all necessary measures to recover these taxes, including the withdrawal of all allocated resources.
The reallocation fee (IPs that are redeemed to the same customer after entering the unregistration process) is 25% of the allocation fee in effect when the reallocation is made, the LIR providing a new service ( "reallocation" ).

7. Confidentiality

Throughout the duration of this agreement, no party may disclose any of the terms of this agreement without the prior consent of the other party.
The customer may not disclose to a third party any information relating to this agreement, even after termination.
The LIR will take all due care to preserve the confidentiality of client data transferred through its servers, will permanently monitor the servers, and stop any unauthorized attempt to access client data as far as it is detected by the security solutions adopted by LIR.
The LIR will be able to present the client's name within the client portfolio.

8. Final provisions

These rules can be changed without prior notice by the customer, they will be made public on the LIR website (ro.nav),, the client agrees to accept the new rules.
These rules are determined by international regulations and are designed to protect Internet resources from inefficient use or for purposes that are inconsistent with applicable laws.
