Does DNS need to be on same subnet?

answer is no, if you more than on vlans or subnets and all are LANS then you can place that one DNS some how(like server VLAN) that all subnets or Lans reaches the DNS server (means DNS server IP should be ping from all Lan IP in different Subnets, you can configure reverse Zone for each Lan or subnet and add host ip …

Should my DNS be the same as my gateway?

Don’t confuse a ‘gateway’ with being a DNS server (at times it can be) but most times it will not be, your gateway may provide you with DHCP (home router) while at the same time forward your DNS requests to your ISPs DNS server (making it seem @ home like your gw + dns are one in the same).

Should servers be on their own subnet?

Keeping your servers on a separate security zone, subnet and VLAN provides network segmentation. This will reduce unnecessary broadcast traffic to your servers and provide more bandwidth between server-to-server traffic.

Can you have 2 DNS servers on the same network?

At a minimum, you’ll need two DNS servers for each Internet domain you have. You can have more than two for a domain but usually three is tops unless you have multiple server farms where you would want to distribute the DNS lookup load. It’s a good idea to have at least one of your DNS servers at a separate location.

Should DHCP servers be required on each subnet of a network?

Reduced network administration DHCP provides centralized and automated TCP/IP configuration. By deploying a DHCP relay agent, a DHCP server is not needed on every subnet.

Should I use 8.8 8.8 DNS?

Can DNS server be on different subnet?

Why do I need 2 DNS servers?

There are two main benefits of using a secondary DNS server: Redundancy and resiliency: Relying on just one DNS server creates a single point of failure. If the primary server fails or is compromised by an attack, prospective visitors can no longer access the desired domain.

Should you have a secondary DNS?

Secondary DNS servers are not mandatory—the DNS system can work even if only a primary server is available. But it is standard, and often required by domain registrars, to have at least one secondary server.

What happens if you have multiple DNS servers?

A Multi-DNS architecture is one that utilizes authoritative DNS nameservers from two or more providers. Most, if not all DNS service providers, use multiple nameservers for high availability and redundancy, allowing them to mitigate most issues without clients even being aware.

How many DHCP server can you have on the same subnet?

However, on the same subnet, you can have two DHCP servers that assign addresses from different ranges.

What happens if you have 2 DHCP servers?

Because two DHCP servers cannot serve the same addresses, address pools defined for a subnet must be unique across DHCP servers. Therefore, when using two or more DHCP servers to serve a particular subnet, the complete list of addresses for that subnet must be divided among the servers.

Can I have 2 DHCP servers on the same network?

After the leases expire, the addresses go back to the address pool and are reused. One of the first misconceptions we may have is that each network must have only one DHCP server. That’s far from true. This notion comes from the fact that we can’t, as a rule, have two hosts on the network using the same IP address.

What is my gateway and DNS server?

Both a proxy server and a gateway route traffic from inside a network to the Internet. A gateway, however, is more like a door to get to the Internet, while a proxy server acts like a wall that bars the inside of the network from being exposed to the Internet.

What is the default gateway?

The default gateway is the path used to pass information when the device doesn’t know where the destination is.
