192.168.1.1 is inside an arrangement of IP location ranges held by RFC 1918 for private non-routable system use. The other such ranges are 10/8 and 172.16/12 communicated in ridiculous between space directing documentation (CIDR). Their proposed reason in 1996 was to save IPv4 address space in situations where internetwork clients had no compelling reason to course bundles outside their own associations and along these lines were assigned non-routable so they could be securely reused in numerous spots inside big business dividers. To that end a few size pieces were held for use by fluctuating size associations as their needs directed: 192.168.1.1 one Class A (10/8), 16 Class Bs (172.16/12) and 256 Class Cs – 192.168/16 is really proposed to be utilized as an adjacent square of 256/24 subnetworks (Class Cs in the more established class-steering wording).
The explanation for holding coterminous pieces of littler systems is that it rearranges directing principles as communicated in the arrangement for IP switches. 192.168.1.1 is feasible for a switch to pass an adjoining set of systems with a solitary tenet where they would somehow or another require one principle for every subnet. On the off chance that a huge system is seen as a tree structure (which they frequently are), at every branch in the tree a solitary principle (or if nothing else an insignificant number of guidelines) can be utilized to speak to steering data for progressively better grained bordering squares. Why this was critical or if nothing else valuable in 1996 is that switches had a generally little limit of working memory in which to keep every one of their tables and on switches interfacing numerous systems it was anything but difficult to fumes memory if directing standards couldn’t be streamlined in some way or another.
A great many people are acquainted with at any rate the 192.168.1.1 prefix since its subnetworks are planned for the littlest of private systems cooked for by RFC 1918 (each/24 contains one system address, one telecast address and 254 tended to accessible for use by hosts). In spite of the fact that utilizing CIDR you could make a subnet for just 2 has in the event that you needed (/30) a/24 caters for every single predictable need of a client not sufficiently learned to reconfigure systems to suit their motivation. Consequently a/24 is constantly the pre-designed system on a shopper system apparatus.
192.168.0/24 was once universally utilized essentially in light of the fact that it was the most minimal numbered/24 subnet in the 192.168/16 square and system directors are for the most part intelligent individuals who have a tendency to distribute from the base of the container up. Exemptions to this practice obviously exist: the 254 (the last) have location is routinely held for the default entryway of a subnet. Correspondingly numerous system administrators allot from the last part of the subnet for system base IPs, for example, different switches, switches, firewalls and so on, and dispense host IPs beginning at 1. Well known customer apparatus makers appear to like 1 as the switch IP for reasons unknown – maybe on the grounds that they think 192.168.1.1 will seem more coherent than a clearly irregular .254 to abdominal muscle initio clients.
The 192.168.1/24 subnet is normally utilized as essentially the following subnet in that/16 piece, however sooner or later it began being utilized as the default range transported on numerous purchaser switches. I suspected at the time this may simply be some pointless security-through-lack of clarity ploy by the producers of mid 802.11 WIFI access indicates or due a few people feeling peculiarly uncomfortable with zero-based tending to. In either case it doesn’t make a difference – any/24 from RFC 1918 is as valuable as some other.
Be that as it may, why 192.168 particularly and not say 189.2?

At the point when written in parallel in “system byte request” 192.168 is 1100000010101000. To be sure the “dabbed decimal” documentation 192.168.0.1 is only an accommodation for people to briefly compose what is really a 32bit number one byte at once and to disentangle the mental number-crunching of determining the host segments of IP locations. “Round” double numbers permit productive location control by bit-covering entire lumps of the location. So why then wasn’t 255.0 picked?
The method of reasoning for the particular prefixes wasn’t tended to in RFC 1918 however the numbers were picked by Jon Postel before that RFC being drafted to supersede his before RFC 1597, wrote while he was still the Czar of Numbers. It appears that his reasons were as per the following:
10.0.0.0/8 was at that point basically a held extent, having been apportioned to the first ARPANet which was no more associated with what had turned into the Internet. Thus it was the most clearly uncontested (just?) Class A system accessible to hold for huge elements’ interior utilize (2^24 locations).
192.168.0 was the following Class C in Jon’s distribution database for Class C arranges that fell on a/16 limit, in this way permitting him to save a/16 of coterminous Class Cs.
172.16/12 IIRC (and this is quite cloudy yet I was taking TCP/IP Internetworking as a course at the time this all happened in 1996) was at that point being utilized for this reason by an expansive element at the time – a University possibly. It might be said in Douglas Comer’s content – I can’t review precisely.
