How to connect to the Vodafone “Super Net Start” tariff plan
Initially, before connecting to a tariff plan, you must purchase the appropriate starter package with support for this program. Next, before using all the benefits of the tariff, you should top up your SIM card balance by a certain amount (80 UAH). New members can switch to another tariff plan within the current program within the first week. In subsequent days, the transition will have a cost equal to the price of the corresponding tariff plan. In the same way, you can reconnect to the “Start” program from other tariffs.
In case of switching to certain tariffs, there are several restrictions: Vodafone music and InstaPASS tariff plan participants have the right to use the program under standard conditions, but the cost will be higher than established. In addition, all functions and capabilities of the previous package are canceled and new conditions come into effect. As for accumulated bonuses and additional funds, they will be retained for use in the new program.
So, you can connect to the “Super Net Start” tariff plan in several ways:
- Go to the official Vodafone SuperNet Start website and activate the transition by sending a request.
- Contact your telecom operator and clarify the connection conditions.
- Enter the special USSD command *444*1#.

conclusions
If a client’s computer at home is already connected to the Internet, and the inability to use a phone with this package as an access point does not frighten him, then SuperNet Unlim is one of the best options on the market. Yes, Kyivstar offers an interesting “Maximum Unlim” tariff, which provides an unlimited number of gigabytes for Internet access without any restrictions, but its cost is 155 UAH/month. Lifecell, in turn, does not have services with an unlimited set of megabytes for accessing the Internet - but there is an interesting life hack tariff. That is why this service is an excellent choice.

Features of connecting to Vodafone SuperNet Start tariff
It is important for a modern person to be on time everywhere, so it is important to use a tariff plan in which you can call relatives in Ukraine, abroad, do business online and spend time usefully. In this case, it is recommended to subscribe to the Vodafone SuperNet Start tariff in 2021.
Cost of services of the SuperNet Pro tariff plan
The basic package of services included in the tariff, costing 125 hryvnia, is valid for 4 weeks. But if you keep an eye on Vodafone shares, you can purchase a starter pack for less.
The range of services in the package is significant, but if it is exhausted, the client can continue to use the usual functions, but taking into account their price:
- 1 minute of conversation with a subscriber of another Ukrainian network - 0.60 hryvnia;
- 10 minutes of conversation with an interlocutor located outside the country - 5 hryvnia;

SMS messages and alternatives
As you may have noticed, when listing services, we did not touch upon such a service as SMS messages, because using SMS in 2021 is quite expensive and costs 50 pieces for 1.5 UAH. That is, even if you send one SMS message, you will be charged an amount of 1.5 UAH, which is not very profitable. For this reason, it would be much more correct to use instant messengers, even for those who have a push-button phone, you can download WhatsApp on a large number of popular phones using the link https://whatsapped.ru/whatsapp-dlya-staryh-modelej-telefonov-samsung.html. For those who have a smartphone, it makes no sense to use SMS messages at all.

Tariffs of the Vodafone SuperNet line under the names Start, Pro and Unlim appeared almost immediately after the information that the company had launched 4G in certain localities of Ukraine. All these proposals are similar to each other, so it is logical to consider them as a whole, and not separately. They pursue a common goal - to satisfy the needs of subscribers for high-speed Internet (4G/3G), as well as voice calls not only within the network, but also to other networks in Ukraine. This is what the terms and conditions of all mentioned tariff plans look like:

A supernetwork
, or
supernet
, is an Internet Protocol (IP) network that is formed, for routing purposes, from the combination of two or more networks (or subnets) into a larger network.
The new routing prefix for the combined network represents the constituent networks in a single routing table entry. The process of forming a supernet is called supernetting
,
prefix aggregation
,
route aggregation
, or
route summarization
.
Supernetting within the Internet serves as a strategy to avoid topological fragmentation of the IP address space by using a hierarchical allocation system that delegates control of segments of address space to regional network service providers.[1] This method facilitates regional route aggregation.
The benefits of supernetting are conservation of address space and efficiencies gained in routers in terms of memory storage of route information and processing overhead when matching routes. Supernetting, however, can introduce interoperability issues and other risks.[2]
OverviewEdit
In Internet networking terminology, a supernet is a block of contiguous subnetworks addressed as a single subnet from the perspective of the larger network. Supernets are always larger than their component networks. Supernetting is the process of aggregating routes to multiple smaller networks, thus saving storage space in the routing table and simplifying routing decisions and reducing routing advertisements to neighboring gateways. Supernetting has helped address the increasing size of routing tables as the Internet has expanded.
Supernetting in large, complex networks can isolate topology changes from other routers. This can improve the stability of the network by limiting the propagation of routing traffic in the event of a network link failure. For example, if a router only advertises a summary route to the next router, then it does not need to advertise any changes to specific subnets within the summarized range. This can significantly reduce any unnecessary routing updates following a topology change. Hence, it increases the speed of convergence resulting in a more stable environment.
Edit
Supernetting requires the use of routing protocols that support Classless Inter-Domain Routing (CIDR). Interior Gateway Routing Protocol, Exterior Gateway Protocol and version 1 of the Routing Information Protocol (RIPv1) assume classful addressing, and therefore cannot transmit the subnet mask information required for supernetting.
Enhanced Interior Gateway Routing Protocol (EIGRP) is a classless routing protocol capable of support for CIDR. By default, EIGRP summarizes the routes within the routing table and forwards these summarized routes to its peers. This may have adverse impact within heterogeneous routing environments with discrete subnets.
The family of classless routing protocols are RIPv2, Open Shortest Path First, EIGRP, IS-IS and Border Gateway Protocol.
ExamplesEdit
A company that operates 150 accounting services in each of 50 districts has a router in each office connected with a Frame Relay link to its corporate headquarters. Without supernetting, the routing table on any given router might have to account for 150 routers in each of the 50 districts, or 7500 different networks. However, if a hierarchical addressing system is implemented with supernetting, then each district has a centralized site as interconnection point. Each route is summarized before being advertised to other districts. Each router now recognizes only its own subnet and the other 49 summarized routes.
The determination of the summary route on a router involves the recognition of the number of highest-order bits that match all addresses. The summary route is calculated as follows. A router has the following networks in its routing table:
192.168.98.0 192.168.99.0 192.168.100.0 192.168.101.0 192.168.102.0 192.168.105.0
Firstly, the addresses are converted to binary format and aligned in a list:
Address | First Octet | Second Octet | Third Octet | Fourth Octet |
192.168.98.0 | 11000000 | 10101000 | 01100010 | 00000000 |
192.168.99.0 | 11000000 | 10101000 | 01100011 | 00000000 |
192.168.100.0 | 11000000 | 10101000 | 01100100 | 00000000 |
192.168.101.0 | 11000000 | 10101000 | 01100101 | 00000000 |
192.168.102.0 | 11000000 | 10101000 | 01100110 | 00000000 |
192.168.105.0 | 11000000 | 10101000 | 01101001 | 00000000 |
Secondly, the bits at which the common pattern of digits ends are located. These common bits are shown in red. Lastly, the number of common bits is counted. The summary route is found by setting the remaining bits to zero, as shown below. It is followed by a slash and then the number of common bits.
First Octet | Second Octet | Third Octet | Fourth Octet | Address | Netmask |
11000000 | 10101000 | 01100000 | 00000000 | 192.168.96.0 | /20 |
The summarized route is 192.168.96.0/20. The subnet mask is 255.255.240.0.
This summarized route also contains networks that were not in the summarized group, namely, 192.168.96.0, 192.168.97.0, 192.168.103.0, 192.168.104.0, 192.168.106.0, 192.168.107.0, 192.168.108.0, 19 2.168.109.0, 192.168. 110.0, and 192.168.111.0. It must be assured that the missing network prefixes do not exist outside of this route.
In another example, an ISP is assigned a block of IP addresses by a regional Internet registry (RIR) of 172.1.0.0 to 172.1.255.255. The ISP might then assign subnetworks to each of their downstream clients, eg, Customer A
will have the range 172.1.1.0 to 172.1.1.255,
Customer B
would receive the range 172.1.2.0 to 172.1.2.255 and
Customer C
would receive the range 172.1.3.0 to 172.1.3.255, and so on. Instead of an entry for each of the subnets 172.1.1.x and 172.1.2.x, etc., the ISP could aggregate the entire 172.1.xx address range and advertise the network 172.1.0.0/16 on the Internet community, which would reduce the number of entries in the global routing table.
