255.255.255.255 = /32 By having a middle reference, it's easier to figure where you are in the range for faster reverse engineering. So basicly, if you know that a /28 is .240, you know that a /29 is .248 etc
The CIDR number comes from the number of 1's in the subnet mask when converted to binary. The common subnet mask 255.255.255.0 is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 1's, or /24 (pronounced 'slash twenty four'). subnet mask of 255.255.255.255 represents all 1s in all 4 octets therefore there are no hosts bits or zeros therefore the destination network address must match exactly [network address not host Oct 04, 2019 · IPv4 Subnet Calculator - 255.255.255.129/28 May 08, 2012 · The host route (single IP address, subnet mask 255.255.255.255) is correct, RAS client will always generate that subnet mask (as mentioned already in http:#26166295. I assume that the duplicate IP is the only problem you have, which is causing all that trouble. Mar 24, 2003 · 211.1.1.255 is the broadcast address for 211.1.1.0/24.\ 255.255.255.255 is the broadcast address for a device that doesn't know (or perhaps just doesn't care) what network it's on. The local TCP/IP stack will convert it to a layer 2 (usually Ethernet) broadcast, so it will go to everyone on the local segment. Forum discussion: I'm trying to configure a Cisco 827 with a public IP issued from Qwest with a subnet of 255.255.255.255, and the Cisco replies with,"e;Bad mask /32 for address xxx.xxx.xxx The recommended version for SRX240 is 11.4R6.6( updated on 31th January 2013) . The same issue is still seen in this version.So even now downgrading to 11.4R4.4 is the only solution or subnet mask of 255.255.255.255 is expected behavior ? Thanks in advance !!
Local link (limited) broadcasts (255.255.255.255) can still be used with 31-bit prefixes. But directed broadcasts are not possible to a 31-bit prefix. This is not really a problem because most routing protocols use multicast, limited broadcasts, or unicasts."

IP/mask Up to the last IP in the subnet Mask Address count Class; a.b.c.d/32 +0.0.0.0: 255.255.255.255: 1: 1 / 256 C: a.b.c.d/31 +0.0.0.1: 255.255.255.254: 2: 1/128 C I did DSL ISP router/SMS work for a year and have never seen a setup like that. That's just bizarre. Not sure what SWBell is doing there. But the IP xx.xx.xx.255 with a subnet of 255.255.255.255 Oct 17, 2019 · The CIDR number comes from the number of ones in the subnet mask when converted to binary. The common subnet mask 255.255.255.0 is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 ones, or /24 (pronounced ‘slash twenty four’). A subnet mask of 255.255.255.192 is 11111111.11111111.11111111.11000000 in binary, or 26 ones 255.255.255.255 and 192.168.1.255 have identical effect if there are no subnets in the network. However, there is a difference when you have broken down your network into subnets. 255.255.255.255 (called as 'Limited-Broadcast') is used by a host to broadcast to all of its immediate neighbors i.e. all those interfaces on the local subnet. Local link (limited) broadcasts (255.255.255.255) can still be used with 31-bit prefixes. But directed broadcasts are not possible to a 31-bit prefix. This is not really a problem because most routing protocols use multicast, limited broadcasts, or unicasts." 255.255.255.255 = /32 By having a middle reference, it's easier to figure where you are in the range for faster reverse engineering. So basicly, if you know that a /28 is .240, you know that a /29 is .248 etc A subnetwork or subnet is a logical subdivision of an IP network.: 1,16 The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses.
