IP v4 query

hellarda · 4 May 2011 at 21:51

just a quick one,

I am sure IPv4 address' consist of xxx.xxx.xxx.xxx

am i correct?

Reason i ask is that today my IT teacher sed it was actually 4 sets of 4 digits?

i.e xxxx.xxxx.xxxx.xxxx

I am pretty sure this is wrong?

cheers

Your teacher is wrong.

hellarda · 4 May 2011 at 21:55

thats exactly what i thought, however when i pointed this out to him he insisted he was right, tbh hes a shocking teacher as it is

He is wrong. Each octet consists of 8 bits, representing 0 to 255, so IPv4 addresses range from 0.0.0.0 to 255.255.255.255

IPv6 uses 4 digits, but its colon separated, is hex not denary and has up to 8 sections.

He/She may have been getting confused with IPv6 which consists of 128 bits because each section has 4 digits/hexi, it looks something like this 2001:0db8:85a3:0000:0000:8a2e:0370:7334

An IPv6 address is shown as eight groups of four hexadecimal digits where each group represents 16 bits (two octets).
The groups are split by a colon ':'

I think your teacher needs education in IT.

I think your teacher probably moved on to ipv6 while you were browsing ocuk and not listening

haha cheers guys, i may show him this :S no he definitely wasn't talking about IPv6 cos he wouldn't know the difference.... he is trying to teach us AS IT....but he is a geography teacher :/ he is t-e-r-r-i-b-l-e :/

Oh dear if this is what the younger generation of IT students is being taught its a good thing were all living longer

I thought my old A Level teacher when I was at college was a 'tard with his shoddy PowerPoints and his poor VB coding.. But not knowing the correct format of an IP address? Oh dear.

Teacher be wrong.

It's a 32 bit number split into 4 octets.

sitting in IT atm, thinking about showing him this thread...

I wouldn't. "hes a shocking teacher as it is"...

(p.s. it is he's)

I used Cisco as a source in one argument with my IT A-level teacher, her response was "Maybe Cisco is wrong". Not likely... Was also amusing on the parents evening (why do they still do this for 6th form?) she said "Trifid appears to pay no attention during class and then disrupts everyone saying something completely irrelevant to the lesson". No dear, I was correcting the misinformation you were saying.
