Business Services - IPv4 and IPv6 addresses

Introduction

Giganet provides both public IPv4 and IPv6 addresses to business broadband and Ethernet leased line services.

As standard, we provide 1 usable IPv4 address with all connections, however we offer multiple IPv4 addresses upon request and at extra charge.

IPv6 is now being rolled out for new customer connections. As standard we provide a /48 IPv6 prefix with each service.

Giganet only provides managed Ethernet leased line services (with a Giganet provided Juniper router). As such we shall allocate the first usable IPv4 address on our router; this shall be the default gateway for your firewall. Therefore when we talk about usable IPv4 addresses, we are factoring in the IPv4 addresses that will be allocated to our equipment.

Standard IPv4 IP address allocation

• Business Broadband:
  • 1 IPv4 - (/32 framed IP over PPPoE)
• Business Leased lines:
  • 1 customer usable IPv4 - (/30 routed block; 1st usable on our Giganet managed router)
• Business leased lines (HA/VRRP high availability design)
  • 3 customer usable IPv4 - (/29 router block; 3 IPv4 required on Giganet's equipment, 1 for each router and 1 HA IPv4)

Standard IPv6 IP address allocation

• All services:
  • /48 IPv6 delegated prefix

HA/VRRP/High Availability Designs

We define HA designs as those including:

• Two Giganet Juniper routers
• Two ELITE leased line circuits (either RO2 resilience or with different carriers)

If you have a service which includes a backup broadband circuit, either with one or two Juniper routers, then this is not classed as HA in terms of IPv4 address allocations/charges. Please refer to the standard Ethernet leased line IPv4 allocations and charges.

Additional IPv4s for multiple customers sharing a Giganet service

Sharing a Giganet connection with multiple end customers (e.g. Serviced offices & sub-let offices to name two obvious examples), is only permitted at the express permission of Giganet.

Where Giganet permits this, and you require multiple IPv4 addresses to provide each end customer their own IPv4 address, then we shall provide additional IPv4 addresses up to the maximum permitted, but at double the charge.

So £6 per IPv4 per month.

Extra IPv4 Allocations and Charges

Business Broadband (Legacy/SuperBOLT/UltraBOLT/UltraBEAM) IPv4 Allocations and Charges

• £3 per IPv4, per month

We can provide individual extra framed /32 IPv4 addresses if your equipment supports this. You don't have to opt for a CIDR subnet (e.g. /29).

A maximum of an additional 8 IPv4s is permitted on our broadband services (CIDR /28 block). We charge for all IPv4s where additional are required for broadband services.

Business Ethernet Leased line (ELITE) IPv4 Allocations and Charges

You get 1 IPv4 included free of charge (/30 block), so we only charge for the additional usable IPv4 addresses.

• /30 IPv4 block - 1 customer usable IPv4 - £0
• /29 IPv4 block - 5 customer usable IPv4s - £12/month
• /28 IPv4 block - 13 customer usable IPv4s - £36/month
• /27 IPv4 block - 29 customer usable IPv4s - £84/month
• /26 IPv4 block and below - not available

Business Ethernet Leased line (ELITE) - High Availability Options - IPv4 Allocations and Charges

You will receive 3 IPv4s included free of charge (/29 block) as we need a larger address space to configure the VRRP redundancy (2 routers + 1 Virtual IP), so we only charge for the additional usable IPv4 addresses.

• /29 IPv4 block - 3 customer usable IPv4s - £0
• /28 IPv4 block - 11 customer usable IPv4s - £24/month
• /27 IPv4 block - 27 customer usable IPv4s - £72/month
• /26 IPv4 block and below - not available

BUSINESS CUSTOMERS ONLY

Our home broadband services only include IPv4 address and additional are not possible. If you require more IP addresses at home, then please consider one of our business broadband services.

Why are there additional charges and limits on IPv4 addresses?

There are only a finite amount of IPv4 addresses remaining, and since 2014, RIPE NCC, the body that is in charge of Internet addressing allocations in the EMEA region have 'run out' of addresses to hand out. Since this time, each ISP is only able to request an additional /22 or block of 1024 IPv4 addresses, and that's it! This is not a lot for each ISP.

IPv4 addresses, (which are the most prevalent on the Internet), were never designed with today’s super connected world in mind. Therefore, there are maximum of ~4.2 billion IPv4 addresses available across the world to share, and a few million of these are reserved and can’t be allocated to end users.

Therefore, we have to be careful to assign large blocks of IPv4s to customers as we only have a finite resource as do every other ISP. We also have to adhere to RIPE NCC rules.

As IPv4s are a scarce resource, and most organisations will only need a single IPv4 address (as most internal IT has been moved to the cloud), we have implemted a small charge for each additional IPv4 required.

Isn't IPV6 the solution?

IPv6 is the next version and has 340 undecillion available IP addresses! (That’s 2¹²⁸)

The bad news is that IPv6 and IPv4 are incompatible, so hence why most people require IPv4 IPs still as most of the Internet hasn’t made the transition yet.

Giganet now is in a position to provide customers IPv6 addressing.

However, most customers will continue to need to use IPv4 IPs for to maintain compatibility.

Network Address Translation and Port Address Translation (NAT & PAT)

To ensure the most efficient use of IPv4 addresses, we recommend that you consider maximising the usage of Network Address Translation (NAT) and Port Address Translation (PAT). NAT allows you to share a single public IPv4 address between multiple internal local area network (LAN) devices. Whereas Port Address Translation (PAT) allows you to map different ports on a single IPv4 address to different internal Local Area Network (LAN) devices.

NAT example:

• Internal LAN 192.168.0/24
• Internal DMZ 10.10.10.0/24

Both these internal subnets and the devices on the LANs can be NAT'd out of a single public IPv4 address.

PAT example:

• HTTPS - TCP 443
• HTTP - TCP 80
• SMTP - TCP 25
• RDP - TCP 3389
• SSH - TCP 22
• SIP - TCP/UDP 5060

Can all share a single public IPv4 address yet be translated to different servers internally on your LAN/DMZ.

TERMS

• Pricing is monthly and excludes VAT at the prevailing rate.
• Minimum term matches the connectivity.
• Charges are in addition to the cost of your connectivity.
• Business customers only.
• Broadband customers are limited to a maximum of 8 additional IPv4 addresses.
• Ethernet leased line customers are limited to a maximum of a /27 CIDR prefix or total that does not exceed a /27 if multiple smaller blocks have been issued.
• Customers do not own the IPv4 blocks.
• IP address are statically assigned, but M12 may need to reassign customer’s IP allocations, but will take all reasonable measures to avoid disrupting the customer.
• If a customer has ordered an RO2 or fully managed failover/backup ELITE (leased line) service, then the included allocation is 1 x /29 block. The maximum allocation is still a /27.
