In the example below, which wildcard mask will cover  the 4 subnets only
192.168.146.0
192.168.147.0
192.168.148.0
192.168.149.0

I though 0.0.7.255 is correct, but it will cover more than those 4 subnets.

Any wildcard mask calculator link, will be helpful.


Thanks

Hello all,
our HTTP packets go via a proxy, unlike the rest of the TCP/IP packets.
so using ping to measure the latency between us and a webserver won't be very accurate. we need to measure latency over HTTP instead of ICMP.
any help ?

Hi,
Our school network has the following:
Sonicwall NSA 250 M Router (acts as gateway and also handles a separate VLAN)
Network address  192.168.1.0 / 24 (subnet mask 255.255.255.0)
Single DC running Server 2016 std (ip 192.168.1.50), handling DNS and DHCP
About 150 endpoints

We're in danger of running out of IPs, so I'm hoping there's a way we can change just the subnet mask and retain the 192.168.1.1 - 192.168.1.254 range while gaining an extra range of IPs on the same, new subnet (for example 192.168.2.x, or .0.x) .  I'm also hoping that changing the subnet mask (but not the IP) of the DC will not cause problems. I know I'll have to reconfigure the subnet mask on any non-dhcp devices (such as network printers and the server).

So I've a couple of questions. What's the best way of doing this?  
Which subnet mask would yield what ranges of IPs?  
Is changing the subnet likely to cause any issues for the server (which I envisage keeping on the same IP?

Thanks in advance.

I'm taking over a new network and the IP scheme is set up as 10.10.x.x/8. I want to change it to a/23. Can I do this within my DHCP and on my router without any changes to my printers and dusktop?

Determine Network Portion and Host portion of  IPV6 IP

Let' say I have this IPV6 IP address.

2001:1234:5678:1234:5678:ABCD:EF12:1234/64

in this case : 2001:1234:5678:1234  is the Network portion and 5678:ABCD:EF12:1234 is the host portion

that one is easy to find.
How about when the CIDR is for instance 53.
Example:


2001:1234:5678:1234:5678:ABCD:EF12:1234/53

Where is the Network portion and where is the host portion ? how do you calculate it ?

Thanks

We have two sites, SiteA and SiteB....the network latency between them is about 15ms.

We want to run an application in both sites, but the vendor supports only 10ms latency between the two sites.

Is there anything we can do to reduce the latency?

Hi

i have a Zultys Zip 57i phone that a user is having a problem with working from home.  It says no network available,

how do i get this phone to work on a home network ?

I decided to buy a pair of Powerline adapters to increase the speed from my modem/router to my PC and my PS4. So i connected one to my router and another one to my PC. Powerline's lights are fine and accordingly, I get green in everything and the middle one, which I assume is like the 'data being sent/received' one, just blinks occasionally (but always green). I've been googling all day and still haven't solved it so I'll just quick resume it:

- LAN connection from router to PC with ethernet cable works perfect
- No problems with WiFi
- Powerline connection to PC gets 'Unidentified network'
- ipconfig /renew doesn't work because i get this message "An error occurred while renewing interface Ethernet : unable to contact your DHCP server. Request has timed out"
- Manually inserting IP and etc. didn't solve it but it could be me (not an expert with internet settings)
- Restarting router and PC doesn't work
- Drivers updated

Here goes my latest 'ipconfig /all':

C:\WINDOWS\system32>ipconfig /all

Any Expert to clarify what the Access List below does ?

R1(config)#access-list 106 permit ip 0.0.0.0 255.255.255.255 255.255.255.192 0.0.0.63  
R1(config)#router bgp 1
R1(config-router)#distribute-list 106 in

Thank you

Understanding Extended-Access List

The Access list below  uses the following arguments:
The Subnet: 172.16.0.0
Wild Card Mask: 0.0.0.0
Subnet Mask: 255.255.255.0
then again :
Wild Card Mask 0.0.0.0




R1(config)#access-list 100 permit ip 172.16.0.0   0.0.0.0   255.255.255.0   0.0.0.0


R1(config)#router bgp 1
R1(config-router)#distribute-list 100 in

Any Expert to clarify why we use all those arguments? and what they mean ?

Thank you

EE,

I have a few servers that I can't RDP into unless it's by IP Address despite the same name and correct DNS records.

Every one also happens to have two Nics where the top binding Nic is on a non routable network. I'm not sure if this is required for clustering or what they have going on but could this cause an issue and could flipping them disrupt any configurations from third party or Microsoft clustering applications?

Thanks in advance
