Do I need a DHCP in an internal network? - networking

Hi and ty for your reading,
I'm a beginner in virtualization and as part of a project I have to configure the IPs of a physical server and 3 virtual machines on Hyper-V in an internal network.
My question is, do I need to have a DHCP because I don't want to have a particular domain?
Which IPs and gateways do you advise me to use, considering my number of machines ?

You should use a subnet like 192.168.99.x with a mask of 255.255.255.0.
Enter your IP manually and you won't need a DHCP.

About my ISP give me a static IPV6 how can i use it and what it mean

Hello guys I got a problem with IPV6 that my ISP give me. I don't really familiar with the IPV6 and this is the info that he gave me.
2001:0E68:5845:7500::/56
2001:0E68:5810:0B23::/64
what are those mean? can I use it to host a web server? can I use it on my DNS like Cloudflare?
/64 1 IPv6 subnet
what does that mean by 1 ipv6 subnet? what is the full address of that ipv6?
and this
/56 256 LAN segments
is it only used by LAN, not on WAN? what I mean is it's like we set up a webserver some IPV4 of our WAN will use at DNS for pointing that domain to ipv4. am so confusing right now please help me explain it to me.
You will typically only use standard /64 networks with IPv6, else you will break some IPv6 features (/127 for point-to-point networks and /128 for loopback addresses are the exceptions).
Your ISP is assigning the /64 network as a transit network to reach your site. The /56 prefix is a delegation, and your router should be able to automatically delegate /64 networks for the individual networks in your site.
The 2001:0E68:5810:0B23::/64 is the full network address for the transit network between the ISP and your site, and you do not normally advertise or use this network in DNS.
The 2001:0E68:5845:7500::/56 is the delegated prefix from which your router can delegate individual standard /64 networks for use within your site. You can use one of the /64 networks to derive your /127 point-to-point and /128 router loopback addresses.
Search for IPv6 Prefix Delegation.
Because these are Global IPv6 addresses, you can assign them to DNS AAAA records. You need to make sure your ISP allows any services you want to provide (very likely with such an address allocation) and be sure to allow any public services (including requests) through your firewall.

Windows access device on different subnet

I am running a device in my local network and want to access it from a different subnet. I can't change the IP address of the device.
I want to access it from a software in windows where I can enter the IP address. How do I configure my windows so that I can access the other subnet? Do I have to do any other configuration on my local network?
I am very new to this stuff so I hope that my question is clear.
Thanks for your help.

The easiest way to communicate to the that device may be change your computer IP to that subnet too. If you don't want to that, there may be some problem complex to solve like NAT traversal since the device may not supply that function and it may not connect to your computer first.

How to use ICS with multiple VMs without losing the explictly set IP addresses for each VM's Network Interface

I am using VMware Workstation on a Windows 10 machine to add a Ubuntu Server and a Windows Server VM. This is to complete a virtual networking (firewall packet filtering) exercise using GNS3. The goal is to have 3 separate networks routed using virtual CISCO routers so I really need to have the IP of machines explicitly set to simulate different networks.
All of this is fine and I can ping from the host to the machines and the machines to the host but I'd also like to somehow be able to access Internet through each of the machines.
When I use Internet Connection Sharing and specify a single virtual adapter it warns me and changes the IP range to 192.168.137.x which is not desirable. When I want to use ICS for both VMs I create a bridged connection and apply ICS to that but again it changes my IP settings.
Is there a way I can share my hosts Internet Connection with each of the machines but keep the IP addresses and ranges I require?
Or, do I have to approach this a completely different way?
BTW, I'm using the Network Adapter type of 'Host Only' rather than Bridged or NAT as I cannot explicitly set IP addresses on those options.
I was overthinking it.
Using VMware I simply had to add an additional device Network Adapter (under VM > Settings) with a type of NAT to enable the VM to share my host's Internet. Of course, the existing interfaces (with the explicitly set IPs) were kept in place so it did not affect my virtual networking environment.

where to get address like 10.0.2.0 in android?

I am trying to get IP address of Android Phone and it shows something like 192.168.0.0.But i need some thing like 10.0.2.0.Are both same?.Can anyone tell me what is the difference and How to get that address?
Thank you
Are you using AVD?
The AVD receives its network address and configuration on the private network from a DHCP server that is integrated into Virtual. The address which the virtual Device receives is usually on a completely different network to the host. As more than one card of a virtual device can be set up to use NAT networking, the first card is connected to the private network 10.0.2.0, the second card to the network 10.0.3.0 and so on.
It is highly unlikely that you have an IP with a 0 at the end because they are mostly used as the Network ID, especially with the 192.168.0.0 adress. The 10.0.2.0 and the 192.168.0.0 Adress are both IP Adresses that are in the private Range, so they are not public. I assume that you get your IP via DHCP so it depends on that DHCP Server what IP you will get. In the end of the day it doesn't really matter if you have an 10.0.xx.xx or a 192.168.0.xx Adress. Maybe I could help you a little more if you tell me why you need a 10.0.2.0 adress?
10.0.0.2 is an IP address found on many local computer networks, particularly business networks.Internet Protocol (IP) version 4 defines certain sets of IP addresses as restricted for private use (not available to be assigned to Web servers or other Internet hosts).

VMware private internal network

I have 4 virtual machines, a client using windows 7 and 3 servers, one of which is a core server installation the other two are standard windows servers. I need to give all machines a static IP address from the range 192.168.0.0/24 and make sure they are all on a private internal network called intnet.
Can anyone give me general guidelines on how I would go about doing this?? As in how to actually set up a private internal network for these machines and then assign each VM to this network?? I am assuming that the network is created in the client windows 7 machine and then the servers are added to this network but i can't seem to find basic information on how to go about this on the net.
Any input appreciated.
VMWare already does all this for you.
It creates:
Two internal subnets
a virtual IP address in the first subnet that is bridged to a real NIC of the host.
an IP address for each VM in the second subnet.
routing between the two subnets.
There is a program called 'Manage virtual networks' that does what it says.
