Hey all,
Just had a quick question. When designing a new network, you basically can decide who gets what IP. I was wondering if there is any "best pratices" or any unwritten rule for picking the IP address for a subnet's default gateway.
Thanks

It is pretty standard to see gateways being the first usable host address in the subnet range.
IE, 192.168.0.0/24 GW 192.168.0.1
I have seen them being the last address as well, but most common is the first from my experiance.Currently PursuingWGU (BS in IT Network Administration) - 52%| CCIE:Voice Written - 0% (0/200 Hours)mikej412 wrote:Cisco Networking isn't just a job, it's a Lifestyle. -
OptionsMosGuy Member Posts: 195There are no unwritten rules for assigning IP's to default gateways. In my experience a lot would depend on the overall design of the network as well as personal preference. It's typically the norm to assign the first address i.e: x.0.1/x.1.1 as previously mentioned. But I've seen a wide variety of addresses used.---

Hi,
We tend to use the following (if HSRP or equivalent is not being used then assume DG is HSRP address):
x.x.x.1 = HSRP
x.x.x.2 = Primary Router
x.x.x.3 = Secondary Router
I have also seen:
x.254 = HSRP
x.252 = Primary
x.253 = Secondary.Regards,
